Crystal structure of octa­kis­(N,N-di­methyl­formamide-κO)europium(III) tetra­cosa-μ₂-oxido-dodeca­oxido-μ₁₂-phosphato-dodeca­molybdate(VI)

The asymmetric unit of the title compound consists of one [Eu(C₃H₇NO)₈]³⁺ complex cation and one α-Keggin-type [PMo₁₂O₄₀] polyanion. Cations and anions are linked through C—H⋯O hydrogen bonds.

Abstract

In the title salt, [Eu(C₃H₇NO)₈][PMo₁₂O₄₀], the asymmetric unit comprises one α-Keggin-type [PMo₁₂O₄₀]³⁻ polyoxidometalate anion and one distorted dodeca­hedral [Eu(C₃H₇NO)₈]³⁺ complex cation. In the crystal, the isolated polyoxidometalate anions are packed into hexa­gonally arranged rows extending parallel to [001]. The complex cations are situated between the rows and are linked to the neighbouring anions through weak C—H⋯O hydrogen-bonding inter­actions, leading to the formation of a three-dimensional network structure.

Chemical context  

Polyoxidometalates (POMs) are versatile metal–oxygen complexes which have attracted inter­est due to their topolog­ical properties and their potential applications in catalysis, photoluminescence, electrochromism and magnetism (Long et al., 2010 ▸; Pope & Müller, 2010 ▸; Coronado & Gómez-García, 1998 ▸). Up to date, a variety of strategies have been developed and used to assemble POM-based hybrid materials by controlling reaction factors such as metal ions, organic ligands, POM species, pH, molar ratio of raw materials or reaction environments (Wang et al., 2013 ▸; Liu et al., 2013 ▸). Even with these approaches, the design and synthesis of new stable polyoxidomolybdate complexes are still challenging.

Herein, we report on the synthesis, UV–vis and IR spectra along with the crystal structure of the hybrid europium(III) POM title compound, [Eu(C₃H₇NO)₈][PMo₁₂O₄₀], (I).

Structural commentary  

The structures of the mol­ecular components of compound (I) are illustrated in Fig. 1 ▸. The [PMo₁₂O₄₀]³⁻ polyoxidoanion of (I) exhibits a classical α-Keggin-type structure. The central P atom is tetra­hedrally surrounded with all four oxygen atoms (O_a) linked to four Mo₃O₁₃ moieties. The latter species are fused together by sharing corner atoms (O_b) and consist of three MoO₆ octa­hedra condensed in a triangular arrangement by sharing edges (O_c). There is also a terminal oxygen atom (O_d) in every MoO₆ octa­hedron. The P—O bond lengths range from 1.521 (5) Å to 1.536 (4) Å and the Mo—O bond lengths from 1.690 (5) Å to 2.438 (4) Å. The O—P—O angles [109.1 (2)–109.8 (3)°] indicate only a slight distortion of the central PO₄ tetra­hedron. The Eu^III cation is coordinated by eight di­methyl­formamide ligands through their oxygen atoms with Eu—O distances from 2.369 (5) to 2.416 (6) Å. These values are comparable to those of related oxido-europium(III) species, e.g for the [Eu(thd)₃(DMF)₂] complex (thd is the ion of 2,2,6,6-tetra­methyl-3,5-hepta­nedione) with Eu—O = 2.494 (5)–2.442 (5) Å (Cunningham & Siever, 1980 ▸). Calculations with the SHAPE software (Alvarez et al., 2005 ▸) indicate that the coordination polyhedron of Eu^III is a slightly distorted dodeca­hedron approaching mol­ecular D _2d symmetry (Casanova et al., 2005 ▸).

Supra­molecular features  

The unit cell content of the title compound is illustrated in Fig. 2 ▸. In the crystal structure of (I), each [Eu(DMF)₈]³⁺ cation is linked to four neighbouring α-Keggin-type [PMo₁₂O₄₀]³⁻ anions through C—H⋯O hydrogen-bonding inter­actions between the methyl groups of the DMF ligands and the terminal-oxygen (O_d) and the bridging-oxygen atoms (O_b,c) of the [PMo₁₂O₄₀]³⁻ anions (Fig. 3 ▸, Table 1 ▸). The C(donor)⋯O_d(acceptor) distances are between 3.174 (10) and 3.541 (11) Å while the C⋯O(_b,c) distances are between 3.289 (11) and 3.473 (12) Å. In the crystal packing, the POM anions are packed into hexa­gonally arranged rows extending parallel to [001] with the [Eu(DMF)₈]³⁺ cations located between the rows (Fig. 4 ▸).

Synthesis and crystallization  

The starting material [(C₄H₉)₄N)₄H₃][PMo₁₁O₃₉] was prepared using a literature method (Combs-Walker & Hill, 1998 ▸). EuCl₃·6H₂O (361.41 mg, 1 mmol) and isonicotinic acid (C₆H₅NO₂) (123.11 mg, 1 mmol) were dissolved in 10 ml of di­methyl­formamide. This solution was added dropwise to a yellow di­methyl­formamide solution of [(C₄H₉)₄N)₄H₃][PMo₁₁O₃₉] (0.33 mmol in 10 ml). The mixture was heated under stirring for 1 h at 333 K. Single crystals of the title compounds were obtained by slow diffusion of 2-propanol through the di­methyl­formamide solution. UV–vis spectrum in di­methyl­formamide: λ_max (nm) 315 and 205.

FT–IR spectroscopy  

The FT–IR spectrum was recorded in the range 4000–400 cm⁻¹ on a Nicolet 470 FT–IR spectrophotometer with pressed KBr pellets.

The FT–IR spectrum of (I) (Fig. 5 ▸) exhibits characteristic bands attributed to the stretching and deformation modes of the Mo—O bond vibration of the [PMo₁₂O₄₀]³⁻ anion in the region 1100–400 cm⁻¹ _. Thus, the asymmetric vibration ν_as(P—O_a), ν_as(Mo=O_d), ν_as(Mo—O_b—Mo) and ν_as(Mo—O_c—Mo) appear at 1065, 951, 885 and 974 cm⁻¹, respectively (Masteri-Farahani & Shahbazi, 2012 ▸). The absorption bands at 1265 and 1657 cm⁻¹ are characteristic of the asymmetric vibration of the C—N and the C=O bonds, respectively. The vibration bands at 1115, 1440, 1385 and 2964 cm⁻¹ are attributed to the vibration ρ(CH₃) (rocking vibration), δ_a(CH₃), δ_s(CH₃) and ν(C-H) of the di­methyl­formamide ligand (Durgaprasad et al., 1971 ▸).

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. Hydrogen atoms were placed in calculated positions and refined as riding atoms: C—H = 0.93 Å and U _iso(H) = 1.2U _eq(C) for methine groups and C—H = 0.96 Å and U _iso(H) = 1.5U _eq(C) for methyl groups. The refined Flack parameter (Parsons et al., 2013 ▸) of −0.015 (7) indicates the correct determination of the absolute structure.

Special details

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 > 2σ(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.
