As part of our ongoing study of different substituents ofAl2N2 ring systems, the synthesis, structuralcharacterization,and spectroscopic studies on several amido derivatives offour-coordinated aluminum are described. ThecompoundsAl2(NEt2)2(NiPr2)2Cl2,1,Al2((NiPr2)4Cl2,2, Al((NiPr2)3,3, Al(NEt2)3, 4,{Al(NiPrH)3}3,5,Al2(NEt2)2(NiPr2)2H2,6, andAlCl3(NiPrH2)2{Al(NH3)(NH2)[Al(NiPrH)(NiPr)Cl]2}2,7, were synthesized by substitution reactionsandcharacterized by mass spectra, IR spectra, elemental analysis, and1H, 13C, and 27Al NMR data.The structuresof three compounds, viz., 1, 6, and7, have been determined by single-crystal X-ray diffractionanalysis.
