Abstract : The organogallium compound, Me2Ga(C5H5) has been observed to react at room temperature or below with primary and secondary amines and phosphines to form Me2GaNH23, Me2GaN(H)(Me)3, Me2GaN(H)(t-Bu)2, Me2GaN(H)(C6H11)2, Me2GaNEt22, Me2GaN(Me)(C6H11)2, Me2GaN(Me)(Ph)2, Me2GaN(Et)(Ph)2, Me2GaP(C6H11)22, Me2GaP(Me)(Ph)3 or Me2GaPPh22 and cyclopentadiene. All new compounds have been fully characterized by their melting points, partial elemental analyses (C and H), 1H NMR, 31P NMR (as appropriate) and IR spectroscopic data and cryoscopic molecular weight studies. The compound Me2GaP(Me)(Ph)3 crystallizes in the trigonal space group R3 with a = 16.526(5)A, c = 10.242(2)A, V = 2421(1)A(3), and Z = 3 (trimeric molecules). The molecule contains a Ga3P3 ring in the chair conformation with phenyl groups in axial positions. The Ga-P distances range from 2.407(4)A to 2.413(6). Gallium-nitrogen and -phosphorus chemistry, X-ray structural study.
