Aqua­[N,N′-ethyl­enebis(o-vanillylideniminato-κ²N,O)]oxovanadium(IV) monohydrate

Reaction of a vanadyl sulfate solution with a tetra­dentate Schiff base ligand derived from the condensation of o-vanillin and ethyl­enediamine in ethanol leads to the title compound, aqua­{6,6′-dimeth­oxy-2,2′-[1,2-ethanediylbis(nitrilo­methyl­idyne)]diphenolato-κ²N,O}oxovanadium(IV) monohydrate, [V(C₁₈H₁₈N₂O₄)O(H₂O)]·H₂O, in which the V^IV atom is six-coordinated by two N atoms and four O atoms in a distorted octa­hedral configuration. In the crystal structure, mol­ecules are linked through O—H...O hydrogen bonding [O...O = 2.788 (4)–2.969 (4) Å] to form a two-dimensional network.
