The amidinato compounds [GaMe2L] [L = RNCR′NR (R, R′ = H, alkyl oraryl)], [GaMe(PhNCPhNPh)2], [GaEt(PhNCMeNPh)2] and [Ga(PhNCRNPh)3] (R = Me or Ph) have been isolated from the reaction of the appropriate gallium trialkyl with 1, 2 and 3 mol of amidine RNCR′N(H)R, respectively. The chloro derivatives [GaCl3{RNCR′N(H)R}] (R = Ph or p-ClC6H4; R′ = Me) and [GaCl2(p-ClC6H4NCMeNC6H 4Cl-p)] have also been prepared. The compounds have been fully characterised, and mass spectrometric data indicate that the volatile dimethylgallium derivatives exist as either monomers or dimers in the gas phase. X-Ray crystallographic studies on [GaMe2(PhNCPhNPh)] and [GaMe(PhNCPhNPh)2] revealed monomeric structures and the presence of chelating amidinate ligands, with distorted tetrahedral and trigonal-bipyramidal co-ordination respectively at the metal centres. Cleavage of the Ga-Me bond occurs on photolysis in the presence of a spin-trapping agent, and thermal decomposition of the solids leads to the formation of gallium nitride.
