Three new heavier group 13 element compounds containing three different substituents, Me3CCH2ClGaPPh2, Me3CCH2BrGaPPh2 and Me3CCH2 ClInPPh2, have been prepared and characterized. All compounds were characterized by partial elemental analysis, cryoscopic molecular weight studies in benzene solution, and NMR and IR spectroscopic data. All three compounds exist as trimeric molecules in solution. NMR spectral data were consistent with the presence of multiple isomers of the trimers. The compound Me3CCH2ClGaPPh23 crystallizes in the acentric space group Pn2la with a 17.7419A, b 13. 9426A and c 21.5748A. Diffraction data were collected on an Enraf-Nonius CAD-4 diffractometer, and the structure was refined to R 4.6 and wR 6.0 for those 2971 reflections with F0 less then or equal to 5 SigmaF0.
