The reaction of Ga(Bu-t)(3) with 1 molar equivalent of a carboxylic ac
id yields the carboxylate bridged dimeric compounds, [(Bu-t)(2)Ga(mu-O
2CR)](2), where R-Ph (I), C6H4-3-CN (2), and C6H4-3-Br (3), respective
ly. Similarly, reaction of Ga(Bu-t)(3) with HSPh yields the thiolate b
ridged compound, [(Bu-t)(2)Ga(mu-SPh)](2) (4). The molecular structure
s of compounds 1, 2, and 4 have been determined by X-ray crystallograp
hy. The Ga ... Ga and Ga-ligand inter-atomic distances for these compo
unds, 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 determ
ine their suitability as linkage groups for self-assembled monolayers.
