(Acetylacetone 3-hydroxy-2-naphthoylhydrazonato-[kappa]3O,N',O')(methoxo-[kappa]O)oxidovanadate(V)

H. W. Wong, K. M. Lo and S. W. Ng

Abstract top

The tridentate Schiff base ligand in the title compound, [V(C16H14N2O3)(CH3O)O], has its O, N and O' atoms spanning three basal positions of the square-based-pyrimidally VV atom. The fourth basal site is occupied by a methoxo ligand, which results from a deprotonated methanol solvent molecule, and the oxido ligand occupies the apical position. The hydroxy H atom forms an intramolecular O-H...N hydrogen bond with an N-atom acceptor site.

Comment top

The reaction of oxovanadium(IV) bis(acetylacetonate), VO(acac)2, with aroylhydrazines in acetonitrile yields vanadium(V) compounds of the formulation V2O3L2 (where L represents the doubly-deprotonated Schiff base). In methanol, the reaction yields Schiff-base complexes having the dinuclear [V(=O)(µ-OMe)2V(=O)]4+ core (Sarkari & Pal, 2009). In the present study, the reaction with a hydroxy-substituted naphthanoic acid hydrazide yields the expected vanadium(V) complex of the doubly-deprotonated Schiff base but a molecule of the solvent is reduced to a methoxide ion (Scheme I). The metal center has square-based pyramidal coordination geometry, with the O,N,O'-atoms of the Schiff base spanning the basal sites, the fourth basal site is occupied by a methoxy ligand and the apical site is occupied by an oxo ligand.

Related literature top

For related vanadium(V) structures, see: Shao et al. (1988). The reaction of oxovanadium(IV) bis(acetylacetonate), VO(acac)2, with aroylhydrazines in methanol yields Schiff-base complexes having the dinuclear [V(=O)(µ-OMe)2V(=O)]4+ core, see: Sarkari & Pal (2009).

Experimental top

Bis(acetylacetonato)oxovanadium(IV) (0.20 g, 0.75 mmol) and 3-hydroxy-2-naphthoyl hydrazide (0.15 g, 0.75 mmol) were heated in methanol (100 ml) for one hour. The brown solution was filtered; slow evaporation of the filtrate afforded brown crystals.

Refinement top

C-bound H-atoms were placed in calculated positions (C—H 0.95 to 0.98 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2 to 1.5U(C). The hydroxyl H-atom was located in a difference Fourier map, and was refined with a distance restraint of O–H 0.84 (1) Å; its isotropic displacement parameter was freely refined. There is no residual electron density near the methoxido O-atom.
