Vanadium Complex of 2-(2‘-Pyridyl)-4,5-dicyanoimidazole Showing Spermicidal and Cytotoxic Properties

Two complexes having the formulas VO(DCIPy)2(H2O)·1.5H2O and VO(DCIPy)2(H2O)·2MeOH have been synthesized
and characterized (DCIPy = 2-(2‘-pyridyl)-4,5-dicyanoimidazolato). The methanol solvated species has been studied
by X-ray diffraction, and single crystals form in the space group P2(1)/n. The hydrated species was studied by
electron paramagnetic resonance spectroscopy in both the solid state and in a frozen solution, and the values of
A∥ examined using the additivity relationship. The hydrated species was shown to exhibit both spermicidal and
cytoxic properties.
