A comparison of vanadyl acetylacetonate complexes of N2O heteroscorpionate ligands that vary systematically in donor set

A series of vanadyl complexes with N2O heteroscorpionate ligands have been prepared and characterized as their cis and trans geometrical isomers both in solution and the solid state. The major difference between the isomers and between the various oxygen atom donors of the N2O scorpionate ligands is in their redox potentials which span almost a volt for this similar set of compounds.
