spectroscopic techniques, elemental analyses, and X-ray diffraction analyses. Complex 7 derived from 1H2, has a C2v quasi-symmetric N4AlO2AlMe2 core structure, while complexes 8 and 10 derived from 2H2 or 4H2, adopt a C2 quasi-symmetric MeN2AlO2AlN2Me core structure, indicating that the steric effect of the ligand plays an important role in the complex formation. Complexes 7–12 are active catalysts for the
