A new Schiff base oxovanadium (IV) complex: [N,N′-bis(4-hydroxysalicylidene)-o-phenylenediamine]oxovanadium(IV) bis(dimethyl sulfoxide) dihydrate

The synthesis and characterization of the title VIV complex of a salicyl­ald­imine, [V(C20H14N2O4)O]·2C2H6OS·2H2O, is described. The reaction of 2,4-di­hydroxy­benz­aldehyde and 1,2-phenyl­enedi­amine with vanadyl sulfate produces a monomeric VIV complex. Its structure reveals that the vanadium(IV) ion is pentacoordinated and situated in a distorted square-pyramidal environment.
