  • Abstract Abstract: Dimeric dimethylAluminum complexes, [Me2Al(m-R)]2 (R= Me, NiPr2, NiBu2, NPh2, NHnBu, OMe) and Al(NiPr2)3 react with carbon dioxide, yielding a series of carbamato aluminum complexes: [Me2Al(m-OCMe3)]2 (1); [Me2Al(m-O2CNiPr2)]2 (2); [Me2Al(m-O2CNiBu2)]2 (3); [Me2Al(m-O2CNPh2)]2 (4); [Me2Al(m-O2CNHnBu)]2 (5); Al4Li2(m4-O)2(m-O2CNiPr2)10 (6). X-ray crystallographic determinations were performed on compounds (2), (3), (4) and (6). The general trends identitide in these structures suggest that depending upon the bonding energy of aluminum with bridge ligand and electron density on bridge ligand. One novel crystal structure (6), Al4Li2(m4-O)2(m-O2CNiPr2)10 , was found from the previous reaction in the presence of lithium chloride. These compounds were characterized with 1H, 13C
    NMR, IR spectroscopy, mass spectrometer, and elemental analyses.
