The reaction of Ga((t)Bu)3 with 1 molar equivalent of a carboxylic acid yields the carboxylate bridged dimeric compounds, [((t)Bu)2Ga(μ-O2CR)]2, where R = Ph (1), C6H4-3-CN (2), and C6H4-3-Br (3), respectively. Similarly, reaction of Ga((t)Bu)3 with HSPh yields the thiolate bridged compound, [((t)Bu)2Ga(μ-SPh)]2 (4). The molecular structures of compounds 1, 2, and 4 have been determined by X-ray crystallography. The Ga...Ga and Ga-ligand inter-atomic distances for these compounds, as well as group 15 and 16 donor bridging ligands, are compared to the values for the surface of GaAs and cubic-GaS in order to determine their suitability as linkage groups for self-assembled monolayers.
