The reaction of antimony(III) chloride, 4,4′-bipyridine (4,4′-bipy) and pyridine-2,6-dicarboxylic acid (pydcH₂), in a 1:2:2 molar ratio in an aqueous solution, resulted in the formation of the title centrosymmetric disordered mixed-valence Sb^III/Sb^V compound, (C₁₀H₉N₂)₂[Sb₂(C₇H₃NO₄)₂(OH)₆]·8H₂O or (4,4′-bipyH)₂[Sb(pydc)(OH)₂(μ-OH)]₂·8H₂O. The seven donor atoms of the (pydc)²⁻ groups and the hydroxido ligands form a distorted pentagonal–bipyramidal arrangement around the Sb^III/Sb^V centers. C—H⋯π stacking interactions between CH groups of the complex dianion and the aromatic rings of the (4,4′-bipyH)⁺ cations, with a distance of 2.89 Å, are observed. In the crystal structure, a wide range of noncovalent interactions, consisting of O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds [D⋯A ranging from 2.722 (2) to 3.137 (3) Å], ion pairing, π–π stacking [centroid–centroid distance of 3.4363 (13) Å] and C—H⋯π interactions, connect the various components into a supramolecular structure.

Comment top

Our research group has recently focused its attention on the one-pot synthesis of water soluble proton transfer compounds that can function as suitable ligands in the synthesis of metal complexes (Aghabozorg et al., 2007a, Aghabozorg et al., 2007b, Aghabozorg et al., 2007c).

The title compound is compossed of a disordered mixed valent Sb^III/Sb^V binuclear dianion, two protonated 4,4'-bipyridines, (4,4'-bipyH)⁺, and eight uncoordinated water molecules (Fig.1 and Fig. 2). The anionic Sb^III/Sb^V binuclear complex is centrosymmetric; the binuclear units are related to one another by an inversion center, which lies at the center of the Sb₂O₂ four membered ring. Each antimony atom is coordinated to a tridentate (pydc)^2- ligand by the carboxylate O-atoms and the pyridine N-atom, and to two terminal hydroxo ligands. Two more hydroxo ligands also serve as bridges between the two Sb^III/Sb^V centers. These bridging hydroxyl groups are remaining from SbOCl, formed during the partial hydrolysis of SbCl₃. The Sb^III/Sb^Vcenters have a distorted pentagonal bipyramidal environment (Fig. 3). Atoms O5 and O6 occupy the axial positions [O5—Sb1—O6 = 172.29 (6) °], whereas atoms N1, O2, O3, O7 and O7ⁱ (i: -x, -y, -z) atoms form the equatorial plane.

In the crystal structure of the title complex, the spaces between layers of {[Sb(pydc)(OH)₂(µ-OH)]₂}^2- anions are filled with (4,4'-bipyH)⁺ cations and water molecules (Fig. 4). The dihedral angle between the two best-planes passing through the aromatic rings of (4,4'-bipyH)⁺ is 31.88 (17) °, which indicates the flexibility of the central C—C bond.

In the crystal structure of the title compound there are C—H···π stacking interactions between the C–H group of the (pydc)^2– fragments andthe aromatic rings of the (4,4'-bipyH)⁺ cations. The C—H···π distance (measured to the center of the pyridine ring) is 2.89 Å for C5—H5···Cg1 (1 - x, 1 - y, 1 - z) with an angle of 132 °. There are also π-π stacking interactions between the aromatic rings of the (4,4'-bipyH)⁺ cations, with a distance of 3.4363 (13) Å for Cg1···Cg1 A (-x, 1 - y, 1 - z) [Cg1 and Cg1 A are the centroids of rings N2/C11—C15 and N2A/C11A—C15A, respectively] (Fig. 5).

In the crystal structure, there are a wide range of non-covalent interactions, consisting O—H···O, N—H···O and C—H···O hydrogen bonds (Table 1 and Fig. 2), ion pairing, π–π and C—H···π stacking interactions (Table 1), all of which connect the various components into a supramolecular structure.

Special details top

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.
