USE OF ME2GA(C5H5) TO PREPARE (ME2GAERR')N (E = N, P) AT OR BELOW ROOM-TEMPERATURE AND THE CRYSTAL AND MOLECULAR-STRUCTURE OF [ME2GAP(ME)(PH)]3

The organogallium compound, Me2Ga(C5H5) has been observed to react at room temperature or below with primary and secondary amines and phosph ines to form [Me2GaNH273, [Me2GaN(H)(Me)]3, [Me2GaN(H)-(t-Bu)]2, [Me2G aN(H)(C6H11)]2, [Me2GaNEt2]2, [Me2-GaN(Me)(C6H11)]2, [Me2GaN(Me)(Ph)]2 , [Me2GaN-(Et)(Ph)]2, [Me2GaP(C6H11)2]2, [Me2GaP(Me)(Ph)]3, or [Me2GaP Ph2]2 and cyclopentadiene. All new compounds have been fully character ized by their melting points, partial elemental analyses (C and H), H- 1 NMR, P-31 NMR (as appropriate), and IR spectroscopic data, and cryos copic molecular weight studies. The compound [Me2-GaP(Me)(Ph)]3 crysta llizes in the trigonal space group R3 with a = 16.526(5) angstrom, c = 10.242(2) angstrom, V = 2421(1) angstrom3, and Z = 3 (trimeric molecu les). The molecule contains a Ga3P3 ring in the chair conformation wit h phenylgroups inaxial positions. The Ga-P distances range from 2.407( 4) to 2.413(6) angstrom.
