In the title complex, [V(C18H11ClN2O2)(CH3O)O(CH3OH)], the VV ion is coordinated by a tridendate 3-chloro-N′-(2-oxidonaphthalen-1-ylmethylidene)benzohydrazidate ligand, one oxido ligand and by O atoms from a methanol and a methoxide ligand, forming a distorted octahedral geometry. The dihedral angle between the benzene ring and the naphthylene ring system is 6.4 (3)°. The deviation of the VV ion from the plane defined by the three donor atoms of the tridentate ligand and the methoxy O atom towards the oxido O atom is 0.323 (2) Å. In the crystal, pairs of intermolecular O—H⋯N hydrogen bonds form centrosymmetric dimers.

2-Hydroxy-1-naphthaldehyde (1 mmol, 0.17 g), 3-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.
Atom H4 was located from a difference Fourier map and refined isotropically. The O4—H4 distance was 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 structural and biological properties (Seena et al., 2008; Bastos et al., 2008; Sarkar & Pal, 2008; Nica et al., 2007). Recently, the author has reported a oxovanadium complex derived from N'-(5-bromo-2-hydroxybenzylidene)-2-chlorobenzohydrazide (Wang, 2011). In this paper, the crystal structure of the title compound is reported.
The VV ion in the title complex, Fig. 1, is six-coordinated by the phenolic O, imine N, and enolic O atoms of the hydrazone ligand, by one oxo O atom, and by two O atoms respectively from a methanol molecule and a methanolate ligand, forming a distorted octahedral geometry. The dihedral angle between the benzene ring and the naphthylene ring system of the hydrazone ligand is 6.4 (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 0.323 (2) Å. The bond lengths and angles at the VV ion 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, pairs of intermolecular O—H···N hydrogen bonds form centrosymmetric dimers (Fig. 2).
