摘要：

Five monomeric gallium(III) compounds, each containing three different ligands, have been prepared by metathetical and/or ligand redistribution reactions and identified as single compounds in benzene solution and in the solid phase, as appropriate. These compounds include GaRCl(acac) (R = Me, Et, Mes (mesityl, C6H2Me3); acac = 2,4-pentanedionato), GaCl[N(SiMe3)(2)](acac), and GaMe[N(SiMe3)(2)](acac). X-ray structural studies of GaMeCl(acac) and GaCl[N(SiMe3)(2)](acac) confirmed the presence of the three different ligands bonded to gallium in these monomeric molecules. The related derivatives GaMeCl(hfac) and GaMesCl(hfaC) (hfac = 1,1,1,5,5,5-hexafluoropentanedionato) were also prepared and characterized, but these compounds slowly decomposed at room temperature.
