Crystal structures of phosphine-supported (η⁵-cyclo­penta­dien­yl)molybdenum(II) propionyl complexes

Solid-state structures are presented for three propionyl complexes of Mo^II featuring piano-stool geometries and supported by tri­aryl­phosphine ligands, showing the effects of para substitution on supra­molecular structure and allowing comparison to the large class of previously reported acetyl complexes.

Abstract

Three cyclo­penta­dienylmolybdenum(II) propionyl complexes featuring tri­aryl­phosphine ligands with different para substituents, namely, dicarbon­yl(η⁵-cyclo­penta­dien­yl)propion­yl(tri­phenyl­phosphane-κP)molybdenum(II), [Mo(C₅H₅)(C₃H₅O)(C₁₈H₁₅P)(CO)₂], (1), dicarbon­yl(η⁵-cyclo­penta­dien­yl)propion­yl[tris­(4-fluoro­phen­yl)phosphane-κP]molybdenum(II), [Mo(C₅H₅)(C₃H₅O)(C₁₈H₁₂F₃P)(CO)₂], (2), and dicarbon­yl(η⁵-cyclo­penta­dien­yl)propion­yl[tris­(4-meth­oxy­phen­yl)phosphane-κP]molybdenum(II) dichloromethane solvate, [Mo(C₅H₅)(C₃H₅O)(C₂₁H₂₁O₃P)(CO)₂]·CH₂Cl₂, (3), have been prepared from the corresponding ethyl complexes via phosphine-induced migratory insertion. These complexes exhibit four-legged piano-stool geom­etries with mol­ecular structures quite similar to each other and to related acetyl complexes. The extended structures of the three complexes differ somewhat, with the para substituent of the tri­aryl­phosphine of (2) (fluoro) or (3) (meth­oxy) engaging in non-classical C—H⋯F or C—H⋯O hydrogen-bonding inter­actions. The structure of (3) exhibits modest disorder in the position of one Cl atom of the di­chloro­methane solvent, which was modeled with two sites showing approximately equivalent occupancies [0.532 (15) and 0.478 (15)].

Chemical context  

Cyclo­penta­dienylmolybdenum(II) complexes featuring carbonyl ligands commonly adopt ‘four-legged piano-stool’ geometries (Barnett & Slocum, 1972 ▸; Kubacek et al., 1982 ▸), and those featuring alkyl co-ligands readily undergo migratory insertion to afford Mo^II acyl complexes upon exposure to phosphines (Barnett & Treichel, 1967 ▸; Butler et al., 1967 ▸). The effect of changing phosphine substituents on this reaction is well established, with bulkier phosphines enhancing the rates of subsequent deinsertion from the acyl complexes, a net deca­rbonylation (Barnett, 1969 ▸; Barnett & Pollmann, 1974 ▸). Most complexes of the type Mo(C₅H₅)(CO)₂(PR ₃)(COR) feature acetyl ligands, though there are limited examples of other acyl complexes that have been structurally characterized (Michelini-Rodriguez et al., 1993 ▸; Murshid et al., 2016 ▸).

We have previously reported synthetic details and solid-state structures for a number of Mo^II acetyl complexes of the type described above (Whited & Hofmeister, 2014 ▸; Whited et al., 2012 ▸, 2014 ▸), examining the effect of changing phosphine substituents on local and supra­molecular features. Consistent with reports on deca­rbonylation reactivity, we have found that the primary impact on mol­ecular structure is observed in the Mo—P bond lengths, with some changes in P—Mo—C bond angles as a result of sterics. Use of tri(2-fur­yl)phosphine, which features heteroatoms as potential hydrogen-bond acceptors, leads to an unusual structure with the acetyl oriented down, away from the cyclo­penta­dienyl ring rather than up toward it as observed in other cases (Whited et al., 2013 ▸), and a similar effect was observed by incorporation of a Lewis-acidic manganese unit to inter­act with the acetyl ligand (Adatia et al., 1986 ▸). Recent use of other potentially hydrogen-bonding phosphine ligands did not lead to the same solid-state effect (Anstey et al., 2020 ▸).

We were inter­ested in extending earlier studies to higher-order alkyl groups at molybdenum, and in this report we describe the synthesis and solid-state structures of related Mo^II propionyl complexes derived from an ethyl precursor and supported by tri­aryl­phosphine ligands differing in their para substitution (–H, –F, and –OCH₃). Although substitution of phosphine aryl groups with electron-withdrawing or -donating groups minimally affects local structure, the supra­molecular organization is substanti­ally affected by non-classical hydrogen-bonding to the fluoro and meth­oxy groups in (2) and (3), respectively.

Structural commentary  

The mol­ecular structures of (1), (2), and (3) are illustrated in Figs. 1 ▸–3 ▸ ▸. All complexes exhibit an overall structure common for CpMo acetyl complexes of this type, with trans-disposed carbonyl ligands. As previously observed for most related acetyl complexes, the acyl C=O points up toward the Cp ring. In the case of (1), this phenomenon could be rationalized by presence of short C4—H4A⋯O1 (2.672 Å) and C4—H4B⋯O2 (2.639 Å) contacts involving the carbonyl ligands that are enabled when the acyl points up. However, the variation of the Mo1—C3—C4—C5 torsion angle across the series [175.31 (12)° for (1), 172.61 (18)° for (2), and 137.17 (10)° for (3)] argues against the general importance of such an inter­action.

Selected geometric parameters for (1), (2), and (3) are presented in Tables 1 ▸–3 ▸ ▸. Complex (2) crystallized with two nearly equivalent mol­ecules in the asymmetric unit, so geometric parameters are presented for both. In general, the three complexes are nearly identical, as might be expected based on the dominant role of sterics in determining structure and the fact that the steric profiles of the three tri­aryl­phosphine ligands are identical. The Mo—P bond length in (2) [2.4692 (4) Å (avg)] is slightly shorter than in (1) or (3) [2.4816 (4) and 2.4745 (3) Å, respectively], which may be related to stronger π-backbonding to the tris­(4-fluoro­phen­yl)phosphine ligand. Stronger backbonding is supported by the observation by infrared spectroscopy of slightly higher-energy carbonyl stretching vibrations for (2) [ν(CO)_avg = 1897 cm⁻¹] compared with (1) and (3) [ν(CO)_avg = 1893 cm⁻¹ for (1), 1890 cm⁻¹ for (3)]. Geometric parameters for all complexes are quite similar to those for the related tri­phenyl­phosphine-supported CpMo acetyl complex (Churchill & Fennessey, 1968 ▸).

Supra­molecular features  

In spite of the similarities among (1), (2), and (3) in their mol­ecular structures, the para substituent of the tri­aryl­phosphine ligand [H for (1), F for (2), OCH₃ for (3)] plays an important role in determining the extended structure. The extended structure of (1) is dominated by non-classical C—H⋯O inter­actions involving its carbonyl ligands. A short C—H⋯O inter­action between O2 and H12 of a phenyl ring (2.36 Å) joins mol­ecules of (1) into centrosymmetrical dimers that are organized into chains along [010] by inter­molecular C15—H15⋯Cg4 (2.952 Å, where Cg4 represents the centroid of the C23–C28 ring) and intra­molecular O2⋯Cg4 (3.295 Å) inter­actions (Fig. 4 ▸, Table 4 ▸). These chains are linked into sheets parallel to (10) through another set of non-classical C—H⋯O inter­actions (2.60 Å) between O1 of the other carbonyl ligand and H6 from a cyclo­penta­dienyl ligand (Fig. 5 ▸).

The tris­(4-fluoro­phen­yl)phosphine-supported derivative (2) features two nearly equivalent mol­ecules in the asymmetric unit exhibiting a non-classical C—H⋯O inter­action between O6 of a propionyl ligand and H15 from a phenyl ring (2.59 Å) and a C—H⋯F close contact between F3 and H53 (2.60 Å). These pairs of mol­ecules are joined into chains along [001] by C34—H34⋯O1 hydrogen bonding (2.38 Å, Fig. 6 ▸, Table 5 ▸)). The mol­ecules are further organized parallel to (010) by C—H⋯F close contacts between F4 and H49 (2.55 Å) and C—H⋯O inter­actions between O3 and H55 (2.53 Å) (Fig. 7 ▸), then further joined along [010] by C—F⋯π inter­actions (F5⋯Cg4 = 3.17 Å, where Cg4 represents the centroid of the C23–C38 ring).

Like complex (1), complex (3) is joined into centrosymmetrical dimers by a C—H⋯O inter­action involving a carbonyl ligand (C8—H8⋯O1, Table 6 ▸), and these are linked into chains along [110] through an additional C—H⋯O inter­action between the propionyl oxygen and a cyclo­penta­dienyl ligand (Fig. 8 ▸). Additional C31—H31B⋯O5 inter­actions along [110], involving a meth­oxy group from the phosphine ligand, join the mol­ecules into a network parallel to (001). This further set of inter­actions involving meth­oxy groups, as well as important close contacts involving the di­chloro­methane solvent, are depicted in Fig. 9 ▸.

Database survey  

The current version of the Cambridge Structural Database (Version 5.41, updated August 2020; Groom et al., 2016 ▸) has fourteen entries corresponding to molybdenum acyl complexes of the general form Mo(C₅H₅)(CO)₂(PR ₃)(COR). The trans-dicarbonyl structure, as observed for (1)–(3), is preferred except in cases where the phosphine and acyl ligands are covalently linked, forcing them to be cis (Adams et al., 1991 ▸; Mercier et al., 1993 ▸; Yan et al., 2009 ▸).

Synthesis and crystallization  

CpMo(CO)₃(CH₂CH₃). This compound was prepared by modification of the method used of Gladysz et al. (1979 ▸), as previously reported by Whited & Hofmeister (2014 ▸) and Anstey et al. (2020 ▸). In a 20 ml scintillation vial equipped with a flea-sized stir bar, [CpMo(CO)₃]₂ (0.1908 g, 0.39 mmol) was dissolved in THF (10 ml). Sodium tri­ethyl­borohydride (0.87 mL of 1.0 M solution in THF, 0.87 mmol) was added dropwise by syringe with vigorous stirring, leading to an immediate color change from purple to green–yellow with evolution of H₂ gas. The reaction was allowed to proceed with stirring for 20 min, and an excess of iodo­ethane (0.098 ml, 1.2 mmol) was added dropwise with stirring and the reaction was allowed to proceed for 6 h. Volatiles were removed in vacuo to afford a yellow–brown film that was stored at 238 K for 1 week. The solid was extracted with pentane (4 × 10 ml) and filtered through a 1 cm pad of activated alumina to afford a yellow solution, and removal of solvent in vacuo afforded CpMo(CO)₃(CH₂CH₃) as a pure yellow powder (0.131 g, 61%). ¹H NMR (400 MHz, CDCl₃): δ 5.28 (s, 5H, Cp ring), 1.72 (q, ³ J _HH = 7.4 Hz, 2H, –CH ₂CH₃), 1.45 (t, ³ J _HH = 7.4 Hz, 3H, –CH₂CH ₃). ¹³C{¹H} NMR (101 MHz, CDCl₃): δ 239.9 (Mo—CO), 227.8 (Mo—CO), 93.0 (Cp ring), 20.4 (Mo—CH₂ CH₃) −3.7 (Mo—CH₂CH₃). IR (CH₂Cl₂, NaCl, cm⁻¹) ν(CO): 2015, 1921 (split).

CpMo(CO)₂(PPh₃)(COCH₂CH₃) (1). In an inert-atmos­phere glove box, CpMo(CO)₃(CH₂CH₃) (0.0803 g, 0.293 mmol) and tri­phenyl­phosphine (0.115 g, 0.440 mmol, 1.5 equiv) were dissolved in aceto­nitrile (5 ml) in a 20 ml scintillation vial equipped with a flea-sized stir bar. The mixture was stirred for 1 week, during which time a bright-yellow precip­itate formed. The yellow solid was isolated by filtration and washed with pentane (2 × 5 ml), then dried in vacuo to afford pure 1. Yellow crystals of 1 suitable for X-ray diffraction were obtained from a concentrated di­chloro­methane solution by vapor cross diffusion with pentane at 238 K. ¹H NMR (400 MHz, CDCl₃): δ 7.50–7.30 (m, 15H, PPh₃), 5.00 (d, J = 1.2 Hz, 5H, C₅ H₅ ), 3.03 (q, ³ J _HH = 7.2 Hz, 2H, C(O)CH ₂CH₃), 0.90 (t, ³ J _HH = 7.2 Hz, 3H, C(O)CH₂CH ₃). ¹³C{¹H} NMR (101 MHz, CDCl₃): δ 267.7 (d, ² J _CP = 11 Hz, Mo—COEt), 238.8 (d, ² J _CP = 24 Hz, Mo—CO), 135.7 (d, ¹ J _CP = 44 Hz, ipso-C of PPh₃), 133.2 (d, ² J _CP = 11 Hz, ortho-C of PPh₃), 130.5 (d, ⁴ J _CP = 2 Hz, para-C of PPh₃), 128.6 (d, ³ J _CP = 11 Hz, meta-C of PPh₃), 96.7 (Cp ring), 58.1 (Mo—COCH₂CH₃), 10.1 (Mo—COCH₂ CH₃). ³¹P{¹H} NMR (162 MHz, CDCl₃): δ 68.4 (s). IR (CH₂Cl₂, NaCl, cm⁻¹) ν(CO): 1935, 1851, 1614 (acet­yl).

CpMo(CO)₂(P(4-FPh)₃)(COCH₂CH₃) (2). In an inert-atmosphere glove box, CpMo(CO)₃(CH₂CH₃) (0.0997 g, 0.36 mmol) and tris­(4-fluoro­phen­yl)phosphine (0.17 g, 0.55 mmol, 1.5 equiv) were dissolved in aceto­nitrile (5 ml) in a 20 ml scintillation vial equipped with a flea-sized stir bar. The mixture was stirred for 1 week, causing a color change to orange, but without formation of any precipitate. Solvent was removed in vacuo, causing precipitation of a yellow solid that was isolated by filtration and washed with pentane (2 × 3 ml) to afford the desired product 2 (0.12 g, 56%). Yellow crystals of 2 suitable for X-ray diffraction were obtained from a concentrated di­chloro­methane solution by vapor cross diffusion with pentane at 238 K. ¹H NMR (400 MHz, CDCl₃): δ 7.41–7.30 (br m, 6H, ortho-C–H of phosphine), 7.14 (td, ³ J _HH ≃ ³ J _HF = 8.6 Hz, ⁴ J _HP = 1.5 Hz, 6H, meta-C—H of phosphine), 4.90 (d, J = 1.2 Hz, 5H, C₅ H₅ ), 2.99 (q, ³ J _HH = 7.2 Hz, 2H, C(O)CH ₂CH₃), 0.90 (t, ³ J _HH = 7.2 Hz, 3H, C(O)CH₂CH ₃). ¹³C{¹H} NMR (101 MHz, CDCl₃): δ 265.4 (d, ² J _CP = 11 Hz, Mo—COEt), 238.2 (d, ² J _CP = 24 Hz, Mo—CO), 164.0 (dd, ¹ J _CF = 253 Hz, ⁴ J _CP = 2 Hz, C—F of phosphine), 135.0 (dd, ² J _CP = 13 Hz, ³ J _CF = 8 Hz, ortho-C of phosphine), 131.3 (dd, ¹ J _CP = 46 Hz, ⁴ J _CF = 4 Hz, ipso-C of phosphine), 116.0 (dd, ² J _CF = 21 Hz, ³ J _CP = 11 Hz, meta-C of phosphine), 96.5 (Cp ring), 58.2 (Mo—COCH₂CH₃), 10.9 (Mo—COCH₂ CH₃). ³¹P{¹H} NMR (162 MHz, CDCl₃): δ 68.5 (s). IR (CH₂Cl₂, NaCl, cm⁻¹) ν(CO): 1938, 1856, 1620 (acet­yl).

CpMo(CO)₂(P(4-MeOPh)₃)(COCH₂CH₃) (3). In an inert-atmosphere glove box, CpMo(CO)₃(CH₂CH₃) (0.113 g, 0.41 mmol) and tris­(4-meth­oxy­phen­yl)phosphine (0.218 g, 0.61 mmol, 1.5 equiv) were dissolved in aceto­nitrile (5 ml) in a 20 nml scintillation vial equipped with a flea-sized stir bar. The mixture was stirred for 1 week, causing precipitation of 3 as a pure yellow powder that was isolated by filtration. Crystals of 3 suitable for X-ray diffraction were obtained from a concentrated di­chloro­methane solution by vapor cross diffusion with pentane at 238 K. ¹H NMR (400 MHz, CDCl₃): δ 7.37–7.23 (br m, 6H, ortho-C–H of phosphine), 7.14 (dd, ³ J _HH = 8.8 Hz, ⁴ J _HP = 1.7 Hz, meta-C—H of phosphine), 4.99 (d, J = 1.2 Hz, 5H, C₅ H₅ ), 3.03 (q, ³ J _HH = 7.2 Hz, 2H, C(O)CH ₂CH₃), 0.89 (t, ³ J _HH = 7.2 Hz, 3H, C(O)CH₂CH ₃). ¹³C{¹H} NMR (101 MHz, CDCl₃): δ 268.6 (d, ² J _CP = 11 Hz, Mo–COEt), 239.2 (d, ² J _CP = 24 Hz, Mo—CO), 161.1 (C—OCH₃ of phosphine), 134.6 (d, ² J _CP = 12 Hz, ortho-C of phosphine), 127.4 (d, ¹ J _CP = 50 Hz, ipso-C of phosphine), 114.0 (d, ³ J _CP = 11 Hz, meta-C of phosphine), 96.6 (Cp ring), 58.0 (Mo—COCH₂CH₃), 10.1 (Mo—COCH₂ CH₃). ³¹P{¹H} NMR (162 MHz, CDCl₃): δ 62.3 (s).

Computer programs: BIS and SAINT (Bruker, 2019 ▸), SHELXT2018/2 (Sheldrick, 2015a ▸), SHELXL2018/3 (Sheldrick, 2015b ▸), Mercury (Macrae et al., 2020 ▸), and publCIF (Westrip, 2010 ▸).

A small number of intense low-angle reflections [three for (1); seven for (2); five for (3)] are missing from these high-quality data sets due to the arrangement of the instrument with a conservatively sized beam stop. The large number of reflections in the data sets (and the Fourier-transform relationship of intensities to atoms) ensures that no particular bias has been introduced.

The structure of (3) exhibits modest disorder in the position of Cl1 of the di­chloro­methane solvent, which was modeled with two sites showing approximately equivalent occupancies [0.532 (15) for Cl1A, 0.468 (15) for Cl1B].

Dicarbonyl(η⁵-cyclopentadienyl)propionyl(triphenylphosphane-κP)molybdenum(II) (1) . Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Dicarbonyl(η⁵-cyclopentadienyl)propionyl[tris(4-fluorophenyl)phosphane-κP]molybdenum(II) (2) . Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Dicarbonyl(η⁵-cyclopentadienyl)propionyl[tris(4-methoxyphenyl)phosphane-κP]molybdenum(II) dichloromethane solvate (3) . Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
