The synthesis of bis(quadridentate)-zirconium (IV) complexes was completed of which two new complexes, bis(N,N'-disalicylidene-cis-1,2,diamino-cyclohexane( zirconium (IV) and bis(N,N'disalicylidene-trans-1,2-diaminocyclohexane)zirconium(IV), were deemed suitable for physical and chemical comparisons to bis(N,N'-disalicylidene-1,2-phenylenediamino)-zirconium(IV). Using H-NMR spectroscopy at low temperatures, it was determined that the interconversion of the cyclohexane moiety of bis(N,N'disalicylidene-cis-1,2-diaminocyclohexane) zirconium(IV) begins to slow whereas, the motions associated with the backbones of the other two complexes do not. Furthermore, using H-NMR spectroscopy, it was determined that heating solutions of pairs of the complexes for four days at 155 C causes the complex to exchange ligands to form mixed-ligand complexes.
