New insight in coordination of vic-dioximes: Bis- and tris(E,E-dioximato)Ni(II) complexes

Bis and tris(E,E-dioximato)nickel(II) complexes have been synthesized and characterized by X-ray diffraction on a single crystal. Absorption spectra studies of these two types of complexes show that they may be converted to each other depend on the pH.
