Abstract top

In the title compound, (C14H13N2)[V(C7H3NO4)O2]·H2O, the VV atom has a distorted trigonal-bipyramidal coordination environment formed by one pyridyl N atom and two O atoms of the [VO2]+ group occupying the equatorial plane, and two carboxylate O atoms occupying the axial positions. O-H...O, N-H...O, O-H...N and C-H...O hydrogen bonds, together with [pi]-[pi] stacking interactions [average centroid-to-centroid distance 3.644 (12) Å], seem to be effective in the stabilization of the crystal structure, resulting in the formation of a three-dimensional supramolecular structure.

Comment top

In recent years, the fundamental coordination chemistry and characterization of vanadium compounds have attracted considerable attention, due to their actions in biological systems. A five coordinated vanadium(V) complex with the same ligand was previously reported (Ranjbar, 2004) in which one (C7H3NO4) anion was attached to a metal center. We herein report the crystal structure of the title compound, (I).

The molecule of (I) contains one (C14H13N2)+ cation, one water molecule and one [V(C7H3NO4)(O2)]- anion, where the vanadium(V) atom has a distorted trigonal bipyramidal coordination environment (Fig. 1, Table 1). The coordinated pyridyl nitrogen atom (N1) and two oxygen atoms (O1V, O2V) of the VO2+ group occupy the distorted equatorial plane, while the two carboxylate oxygen atoms (O1 and O3) occupy the axial positions around the central atom.

The V1—O1V [1.6228 (14) Å] and V1—O2V [1.6158 (14) Å] bonds are shorter than V1—O1 [2.0132 (13) Å] and V1—O3 [1.9842 (13) Å] bonds, due to the formation of double bonds. The water molecule resides between two ionic units making a bridge-like hydrogen bond. Beside the classic hydrogen bonds, there are also C—H···O type hydrogen bonds (Table 2), which are responsible for stabilization of the crystal network. Each vanadium(V) complex is attached to the neighboring complex and four (C14H13N2)+ units via C—H···O interactions. These interactions, coming inconcert, make an infinite layers which could be described by R22 (10), C22 (15) and R33(13) graph set descriptors (Fig. 2). Furthermore, considering the average values for intercentroid [3.644 (12) Å] and interplanar [3.297 (16) Å] distances for (C14H13N2)+ ions [symmetry codes: x, y, z; x - 1, y, z; -x, -y, -z + 2; -x - 1, -y, -z + 2], the π-π stacking interaction between cations can be established. Thus, the three-dimensional supramolecular structure for (I) is confirmed.

Experimental top

A pale yellow colored vanadium(V) complex of cation and anion as a proton transfer agent, the title compound, (I), was isolated at pH = 3.0 by stirring an aqueous mixture of the ligand [2,9-dimethyl-1,10-phenathroline (21.2 mg) and pyridine-2,6-dicarboxylic acid (13.9 mg) in water (10 ml)] with 0.5 molar equivalent of vanadium(III) chloride (8.1 mg) at room temperature (yield; 1.79 mg, 73%, m.p. 450 K). Slow evaporation of the solvent during two weeks resulted in X-ray quality crystals. Elemental analysis revealed that one molecule of water is associated as solvate.

Refinement top

H atoms were positioned geometrically, with N—H = 0.88 Å (for NH), O—H = 0.85 Å (for OH2) and C—H = 0.95 and 0.98 Å for aromatic and methyl H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C,N,O), where x = 1.5 for water and methyl H, and x = 1.2 for all other H atoms.

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.
