Abstract

In the title compound, [VO2(C6H4NO 2)(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-H⋯O, C-H⋯O and O-H⋯O hydrogen bonds involving the solvent water molecule.
