Synthesis and Characterization of (Me3SiCH2)3M.E(SiMe3) (M= Ga, E = P or As; M = In, E = P). X-ray Crystal Structures of (Me3SiCH2)Ga.P(SiMe3)3 AND (Me3Si CH2)3In.P(SiMe3)3.

Recent investigations in our laboratory have centered on the facile formation of the 13-15 bond by reactions of organo-group 13 reagents with either the silylpnicogen compounds ESiMe33 E P or As or their monolithium salts in solution. As a result of our efforts, we have isolated several new compounds containing the 13-15 covalent bond. Included in our results are compounds which exhibit dimeric structures in the solid-state and those in which two group 13 centers are bridged by a halogen atom and a group 15 atom. In addition, adducts of the type R3M.ESiMe33R Me3SiCH2, M In, E As3 R Ph3 or C6F54, M Ga, E As or P have been isolated in our laboratory. Adducts of this type may find utility as potential single source precursors to binary 13-15 semiconductors however, a review of the literature finds limited structural and thermal analysis data for adducts of this type. We report herein the synthesis, characterization, and thermal analysis of three new main group adducts, Me3SiCH2Ga. PSiMe33 1, Me3SiCH23Ga.AsSiMe33 2, and Me3SiCH23In.PSiMe33 3. jg p. 2
