The VV atom in the title complex, [V(C14H8BrClN2O2)(CH3O)O(CH3OH)], is six-coordinated by one phenolate O, one imine N and one enolic O atom of the hydrazone ligand, one oxide O atom, one methanol O atom and one methoxide O atom in a distorted octahedral geometry. The dihedral angle between the two benzene rings of the hydrazone ligand is 13.2 (3)°. The deviation of the V atom towards the oxide O atom from the plane defined by the three donor atoms of the hydrazone ligand and the methoxy O atom is 0.318 (2) Å. Bond lengths are comparable with those observed in similar oxidovanadium(V) complexes with hydrazone ligands. In the crystal, pairs of molecules are linked through intermolecular O—H⋯N hydrogen bonds, forming dimers.

5-Bromosalicylaldehyde (1 mmol, 0.20 g), 2-chlorobenzohydrazide 1 mmol, 0.17 g), and VO(acac)2 (1 mmol, 0.26 g) were mixed in methanol (30 ml). The mixture was boiled under reflux for 2 h, then cooled to room temperature. Brown block-like single crystals, suitable for X-ray diffraction, were formed after slow evaporation of the solution in air for a few days.
H5 atom was located from a difference Fourier map and refined isotropically. The O5—H5 distance is restrained to 0.85 (1) Å. The remaining hydrogen atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H distances of 0.93–0.96 Å, and with Uiso(H) set at 1.2Ueq(C) and 1.5Ueq(Cmethyl).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Hydrazone compounds and their oxovanadium complexes have received much attention due to their structures and biological properties (Seena et al., 2008; Bastos et al., 2008; Sarkar & Pal, 2008; Nica et al., 2007). In this paper, the title new oxovanadium(V) complex with a hydrazone ligand is reported.
The VV atom in the title complex, Fig. 1, is six-coordinated by one phenolic O, one imine N, and one enolic O atoms of the hydrazone ligand, by one oxo O atom, and by two O atoms respectively from a methanol molecule and a methoxide ligand, forming a distorted octahedral geometry. The dihedral angle between the two benzene rings of the hydrazone ligand is 13.2 (3)°. The deviation of the V atom from the plane defined by the three donor atoms of the hydrazone ligand and the methoxy O atom towards the oxo O atom is 0.318 (2) Å. The coordinate bond lengths and angles (Table 1) are comparable with those observed in similar oxovanadium(V) complexes (Kurup et al., 2010; Rajak et al., 2000; Grüning et al., 1999; Mondal et al., 2009). In the crystal structure, adjacent two molecules are linked through intermolecular O—H···N hydrogen bonds (Table 2), to form a dimer, as shown in Fig. 2.
