title: (Acetyl-acetone isonicotinoylhydrazonato-κO,N',O')dioxidovanadate(V) monohydrate.
abstract: The hydrazone anion in the title compound, [V(C(11)H(12)N(3)O(2))O(2)]·H(2)O, is zwitterionic as its pyridyl N atom is protonated; the O, N and O' atoms span the axial-equatorial-axial positions of the trigonal-bipyramidal coord-in-ation polyhedron of the metal atom. All non-H atoms lie on a crystallographic mirror plane apart from the oxide ligands, which are related by mirror symmetry. The pyridinium N atom acts as a hydrogen-bond donor to the solvent water mol-ecule, which is in turn a hydrogen-bond donor to the both oxide ligands. These hydrogen-bonding inter-actions give rise to a three-dimensional network motif.
