unsubstituted Salophan led to a complex product mixture for both titanium and zirconium. The methyl-substituted ligand led to a clean complex only with zirconium, and the other ligands gave well-defined coordination chemistry with both metals. NMR analysis indicated that these Salophans acted as dianionic ligands, giving rise to hexa-coordinate complexes of C2-symmetry. X-ray analysis of three complexes supported
