Poly[[2-(3-pyridinio)-1H,3H +-benzimidazolium] [μ4-oxido-di-μ3-oxido-tetra-μ2-oxido-hexa­oxidotetra­molybdenum(VI)]]

Abstract

The reaction of MoO3 with 2-(3-pyrid­yl)benzoimidazole and water in the presence of MnSO4·5H2O at 453 K under hydro­thermal conditions afforded the title compound, {(C12H11N2)[Mo4O13]}n, in which infinite molybdenum oxide anionic chains are charge-balanced by diprotonated 2-(3-pyrid­yl)benzoimidazole (H23-PBIM2+) cations. Eight [MoO6] octa­hedra are edge-shared, forming compact octa­molybdate subunits which are connected through pairs of Mo—O—Mo bridges into extended one-dimensional arrays propagating along the a-axis direction. The asymmetric unit of the metal oxide chain contains one half of the octa­molybdate unit, denoted [Mo4O13], the other half being generated by an inversion center. These molybdenum oxide chains are further connected through the 2-(3-pyridinio)benzoimidazolium cations into a three-dimensional network via N—H(...)O hydrogen bonds. In addition, neighbouring diprotonated cations are arranged in a head-to-tail fashion with a plane-to-plane separation of 3.63 (10) Å, indicating the existence of weak aromatic π–π stacking inter­actions.

Comment

The exploration of metal oxide-based inorganic-organic hybrid materials is of contemporary interest in the fields of solid state chemistry, not only because of their fascinating properties and potential applications in many fields, such as catalysis, sorption, electrical conductivity, magnetism and optical materials (Pope & Müller, 1991, Pope, 1983). Owing to their versatile stoichiometry, different structure, and high reactivity (Kong, 2004), molybdenum polyoxoanions are good candidates to function as building blocks for inorganic-organic hybrid materials. Through exploiting the strategy of synergistic interaction between organic and inorganic components, many examples of molybdenum oxide-based solid materials with one-dimensional chain, two-dimensional sheet and three-dimensional framework structures have been successfully synthesized (Hagrman et al., 1999, Lu et al., 2002). The organic components often function as charge compensating cations or as a linking bridges, to extend the molybdenum oxide building units into multi-dimensional networks. We report here the synthesis and crystal structure of the title compound, in which the organic component acts as a charge compensating cation.

The structure of title compound consists of an infinite molybdenum oxide chain which is charge balanced by diprotonated H23-PBIM2+ cations. As shown Fig. 1, every Mo atom is coordinated octahedrally by six O atoms. These can be divided into four groups according to their coordination environments: (i) Mo—O(t), 1.682 (5)–1.718 (5) Å; (ii) Mo—O(µ2-O), 1.776 (5)–2.229 (6) Å; (iii) Mo—O(µ3-O), 1.875 (5)- 2.345 (5) Å; (iv) Mo—O(µ4-O), 1.956 (5)–2.416 (5) Å (Table 1).

The asymmetric unit of the metal oxide chain contains one half of the octamolybdate unit, denoted as [Mo4O13], the other half is generated by the inversion center. Four asymmetric [MoO6] octahedra are edge- shared to form [Mo4O13]2- unit. Two [Mo4O13]2- units are stacked together by edge-sharing to give rise to γ-[Mo8O26]4- octamolybdate clusters, which are linked together to form infinite one- dimensional chains propagating along the a-direction through sharing pairs of common vertices. Therefore, the molybdenum oxide chain may be regarded to be constructed from octamolybdate units joined at two oxo groups or from two groups of cis-edge-sharing tetranuclear units fused at two common corners. The octamolybdate chain in the title compound is structurally analogous to those found in [Me—NC5H5]4[Mo8O26] (Modec et al., 2003), [H2enMe]2[Mo8O26] (Xiao et al., 2005), and [NH3(CH2)2NH3]2[Mo8O26] (Chakrabarti & Natarajan, 2002).

In the solid state of the title compound, the one-dimensional molybdenum oxide chains are held together and extended to three-dimensional framework via strong N—H···O hydrogen bonding and weak aromatic π-π stacking interactions. As illustrated in Fig. 3, one of the imino groups and the pyridyl group in the H23-PBIM2+ ligands participate in the intermolecular hydrogen bonding with two µ2-O atoms of the molybdenum oxide chains. The N···O separations are 2.639 (8) and 2.614 (8) Å with both H···O distances are 1.78 Å, falling into the normal range of the strong hydrogen bond interactions. The bond angles are 176.3 and 163.6 °, respectively. In addition, the neighbouring diprotonated H23-PBIM2+ ligands along the a-direction are arranged in a head-to-tail fashion with a plane-to-plane separation of 3.63 (10) Å, indicating the existence of weak aromatic π-π stacking interactions (Janiak, 2000).

Experimental

A mixture of MoO3, MnSO4.5H2O, 2-(3-pyridyl)benzoimidazole and H2O in the molar ratio 1.0:1.2:1.0:1835 was sealed in a 18 ml Teflon-lined Parr acid digestion bomb and heated for 3 days at 453 K and autogeneous pressure. After allowing the reaction mixture to cool down to room temperature, colorless needle-like crystals of title compound were collected, washed with water and air dried.

Refinement

The positions of all hydrogen atoms were generated geometrically (C—H and N—H bonds fixed at 0.96 Å and 0.86 Å, respectively), assigned isotropic thermal parameters, and allowed to ride on their respective parent C or N atoms before the final cycle of least-squares refinement.

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 > 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.
