Abstract

In the title compound, [VO(C16H16N2O2)(H2O)]NO3·0.76H2O, the V atom has a distorted octahedral coordination geometry with a long V—O(water) bond, 2.225 (1) Å, trans to V=O, 1.594 (1) Å. The V atom is 0.260 Å out of the plane defined by the N and O atoms of the bis­(salicyl­idene)­ethyl­enediaminate ligand and is displaced towards the vanadyl O atom. The coordinated water mol­ecule is hydrogen bonded to one O atom of the nitrate ion so that pairs of cations are linked by two O—H⋯O⋯H—O bridges to give neutral centrosymmetric dimers. This is a different bridging arrangement from that found in either of the polymorphs of the an­hydro­us compound. There is also a weak hydrogen bond between a nitrate O and the partially occupied water of crystallization.
