L. E. Khoon, T. S. Guan and B. M. Yamin

Abstract: In the title compound, [VO₂(C₆H₄NO₂)(C₆H₅NO₂)]·H₂O, one of the two pyridine-2-carboxylate ligands chelates to the V atom in a bidentate manner, via the carboxylate O atom and the N atom of the pyridine ring. The second pyridine-2-carboxylate ligand coordinates to the V atom only via the carboxylate O atom, while the N atom of the pyridine ring is protonated. The coordination geometry of the V atom is distorted trigonal-bipyramidal. The crystal packing is stabilized by intermolecular N-HO, C-HO and O-HO hydrogen bonds involving the solvent water molecule.
