Bis(tetra­ethyl­ammonium) bis­(dimethyl­formamide)­tetra­kis­(μ-N,2-dioxido­benzene-1-carboximidato)penta­copper(II)

Abstract

The title compound, (C₈H₂₀N)₂[Cu₅(C₇H₄NO₃)₄(C₃H₇NO)₂], abbreviated as (TEA)₂[Cu^II(12-MC_{Cu^II N(shi)}-4](DMF)₂ [where TEA is tetra­ethyl­ammonium, shi³⁻ is salicyl­hydroximate (or N,2-dioxidobenzene-1-carboximidate) and DMF is N,N-dimethyl­formamide], contains five Cu^II ions. Four of the Cu^II ions are members of a metallacrown ring (MC), while the fifth Cu^II is bound in a central cavity. Two of the ring Cu^II ions are five-coordinate with distorted square-pyramidal geometry. The coordination sphere is composed of two shi³⁻ ligands and one DMF mol­ecule. The other two ring Cu^II ions and the central Cu^II ion are four-coordinate with square-planar geometry. The coordination spheres of these ions are only composed of shi³⁻ ligands. The charge of the [Cu^II(12-MC_{Cu^II N(shi)}-4]²⁻ unit is balanced by two uncoordinated TEA⁺ countercations. The structure shows severe static disorder with the metallacrown, the tetra­ethyl­ammonium cations and the DMF solvent mol­ecule all disordered over each of two mutually exclusive sites, with occupancy rates for the major moieties of 0.6215 (6) for the metallacrown, 0.759 (3) for the tetra­ethyl­ammonium ion and 0.537 (6) for the DMF mol­ecules. The metallacrown unit is located on a crystallographic inversion center and disordered about a non-crystallographic twofold axis. The DMF mol­ecule and the tetra­ethyl­ammonium ion are disordered about a non-crystallographic twofold axis and pseudo-inversion center, respectively.

Comment

Since the identification of metallacrowns (MC) in 1989 (Pecoraro, 1989), these inorganic crown ether analogues have proved to be very diverse molecules (Mezei et al., 2007; Pecoraro et al., 1997). Metallacrowns can behave as single-molecule magnets, have potential use as MRI contrast agents, and can selectively bind cations or anions (Mezei et al., 2007). In addition to being inorganic structural and functional analogues of crown ethers, the naming scheme for the two molecules is very similar. For example, the name 12-MC-4 indicates that there are 12 atoms in the metallacrown ring and there are 4 oxygen atoms in the ring that can potentially bind to a central metal ion. A complete nomenclature description for metallacrowns can be found in Pecoraro et al. (1997).

Copper(II) 12-MC-4 structures are common (Mezei et al., 2007), and the structures tend to be fairly planar. The planar structures are generated by placing the ring Cu^II ions at 90^o relative to each other. This placement is typically achieved by selection of a ligand, such as salicylhydroxamic acid, that can form fused five- and six-membered chelate rings. However, planar structures have been observed for other sized fused chelate rings (Mezei et al., 2007). One planar Cu^II[12-MC_Cu^II-4]²⁺ has been used to build a two-dimensional chiral solid (Bodwin & Pecoraro, 2000).

Herein we report the synthesis, IR data, and the single-crystal X-ray structure of the title compound,C₂₈H₁₆Cu₅N₄O₁₂, 2(C₈H₂₀N), 2(C₃H₇NO) abbreviated as (TEA)₂[Cu(12—MC_Cu^IIN(shi)-4](DMF)₂, (1), where TEA is tetraethylammonium, shi^3- is salicylhydroximate, and DMF is N,N-dimethylformamide. The single-crystal X-ray structure of a related molecule, (TMA)₂[Cu(12—MC_Cu^IIN(shi)-4]^.DMF (2, where TMA is tetramethylammonium), has previously been reported by Gibney et al. (1994), and the synthesis of another related molecule, (TEA)₂[Cu(12—MC_{Cu^IIN(d2shi)}-4)]^.2DMF^.H₂O (where d₂shi is 3,5-dideuteriosalicylhydroximate), has been described by Gibney et al. (1994).

Compound 1 is fairly planar, which is typical of Cu^II 12-MC-4 structures (Fig. 1–3; Macrae et al., 2006). The structure consists of a [Cu^II—N—O] repeat unit around the MC ring, and the MC binds a Cu^II in the central cavity. Cu1 is located in the central cavity and is four-coordinate with square planar geometry. Cu2, Cu3, Cu2ⁱ and Cu3ⁱ compose the MC ring (symmetry operator (i): -x + 1, -y + 1, -z + 1). Cu2 is five-coordinate with distorted square pyramidal geometry with τ equal to 0.02 (τ = 0 for square pyramidal geometry and τ = 1 for trigonal bipyramidal geometry (Addison et al., 1984). The basal portion of the geometry is composed of two shi^3- ligands that bind with oxygen and nitrogen atoms. The apical position is filled by a DMF molecule which binds with an oxygen atom (O7 and O7b). The Cu2—O7 bond distance is 2.763 (14) Å, and the Cu2—O7b bond distance is 2.696 (17) Å. Cu3 is four-coordinate with square planar geometry, and the coordination is composed of two shi^3- ligands that bind with oxygen and nitrogen atoms. An uncoordinated TEA countercation is located in the lattice. In addition, the structure of 1 shows severe static disorder as the metallacrown, TEA, and DMF are disordered over two mutually exclusive sites (Figs. 4–6, Farrugia, 1997).

Compounds 1 and 2 are similar planar 12-MC-4 molecules. Compound 2 also consist of a [Cu^II—N—O] repeat unit with a Cu^II ion bound in the central cavity (Gibney et al., 1994). However, in 2 all of the ring Cu^II ions are four-coordinate with square planar geometry. The geometry about the ring Cu^II ions in 2 is different compared to 1. In 1 the DMF molecules are bound to two of the ring Cu^II ions, which gives these Cu^II ions a distorted square pyramidal geometry (Fig. 2). In 2 the DMF molecule does not bind to any of the Cu^II ions, but instead the DMF is present only in the lattice (Gibney et al., 1994).

Experimental

Copper(II) acetate monohydrate (99+%) was purchased from Sigma-Aldrich, salicylhydroxamic acid (H₃shi, 99%) was purchased from Alfa Aesar, tetraethylammonium acetate (99%) was purchased from Acros Organics, absolute diethyl ether was purchased from EMD Chemicals, and N,N-dimethylformamide (ACS grade) was purchased from Fisher Scientific. All reagents were used as received and without further purification.

Copper(II) acetate monohydrate (0.625 mmol), salicylhydroxamic acid (0.5 mmol), and tetraethylammonium acetate (1.0 mmol) were mixed in 10 mL of DMF. Upon mixing the solution turned a dark green color. After stirring overnight, the solution was gravity filtered. No precipitate was observed, and the filtrate remained a dark green color. X-ray quality crystals were grown via diffusion of diethyl ether at 277 K (4 ^oC). The product was a dark green diamond-shaped crystal, and after washing the filtered product with cold DMF, the percent yield was 36% (0.0607 g) based on copper(II) acetate monohydrate. Elemental analysis for C₅₀H₇₀Cu₅N₈O₁₄ [FW = 1325.74 g/mol] found % (calculated); C 45.21 (45.33); H 5.33 (5.33); N 8.37 (8.46).

Refinement

The structure of 1 shows severe static disorder. The anionic metallacrown, the tetraethylammonium and the solvent DMF molecules all show disorder over each two mutually exclusive sites with different occupancy ratios. The refined values are 0.6215 (6) to 0.3785 (6) for the metallacrown, 0.759 (3) to 0.241 (1) for the tetraethylammonium ions and 0.537 (6) to 0.463 (6) for the DMF molecules. The metallacrown is disordered by a non-crystallographic two-fold axis, as is the DMF molecule. The tetraethylammonium is disordered by a pseudo-inversion center. Equivalent bonds in disordered sections of the molecules were restrained to be similar (standard deviation 0.02 Å). The atom O7 and O7b were restrained to be approximately isotropic (standard deviation 0.01 Ų), and the ADPs of the atoms C18b and C22, O7 and O7b, and N4 and N4b were each constrained to be the same. Aromatic benzene rings were constrained to resemble ideal hexagons with C—C distances of 1.39 Ångstroms.

Hydrogen atoms were placed in calculated positions with C—H = 0.95 (aromatic), 0.98 (methyl) and 0.99 Å (methylene) and were refined with Uĩso~(H) = 1.5 U_eq(C) for methyl H atoms and 1.2 U_eq(C) for methylene and aromatic moieties.

Special details

Experimental. The structure of 1 shows severe static disorder. The anionic metallacrown, the tetraethylammonium, and the solvent DMF molecules all show disorder over each two mutually exclusive sites with different occupancy ratios. The refined values are 0.6215 (6) to 0.3785 (6) for the metallacrown, 0.759 (3) to 0.241 (1) for the tetraethylammonium ions and 0.537 (6) to 0.463 (6) for the DMF molecules. The metallacrown is disordered by a non-crystallographic two fold axis, as is the DMF molecule. The tetraethylammonium is disordered by a pseudo-inversion center. Equivalent bonds in disordered sections of the molecules were restrained to be similar (standard deviation 0.02 Å). The atom O7 and O7b were restrained to be approximately isotropic (standard deviation 0.01 Å2), and the ADPs of the atoms C18b and C22, O7 and O7b, and N4 and N4b were each constrained to be the same. Aromatic benzene rings were constrained to resemble ideal hexagons with C—C distances of 1.39 Å.IR bands (cm-1): 1605(s), 1572(s), 1526(s), 1437(m), 1389(s), 1319(s), 1254(s), 1097(m), 1024(m), 943(m), 742(m), 684(m), 657(m), 582(m), 476(m).

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

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
