Catecholate and Semiquinone Complexes of Vanadium. Factors That Direct Charge Distribution in Metal-Quinone Complexes Marion E. Cass, Nancy Rowan Gordon, and Cortlandt G. Pierpont* Received May 13, I986 Semiquinone and catecholate complexes of vanadium have been studied with tetrachloroquinone and 3,5-di-tert-butylquinone ligands. Crystallographic characterization has been carried out on the sodium salt of V(DBCat)
