(Methanol-κO)(methano-lato-κO)oxido{N'-[1-(2-oxidonaphthalen-1-yl-κO)ethyl-idene]nicotinohydrazidato-κN',O}vanadium(V).

ABSTRACT

The title oxovanadium(V) complex, [V(C(18)H(13)N(3)O(2))(CH(3)O)O(CH(3)OH)], was obtained by the reaction of 1-(2-hy-droxy-naphthalen-1-yl)ethanone, nicotinohydrazide and vanadyl sulfate in methanol. The V(V) atom is six-coordinated by the N,N,O-tridentate Schiff base ligand, one methano-late O atom, one methanol O atom and one oxide O atom, forming a distorted octa-hedral geometry. The methanol O atom lies trans to the V=O group. The dihedral angle between the pyridine ring and the naphthalene ring system is 31.52 (10)°. In the crystal, inversion dimers linked by pairs of O-H⋯N hydrogen bonds occur.
