Full title: Chemistry of mesitylgallium(III) derivatives as arene ligands in metal carbonyl complexes. Crystal and molecular structures of [(CO)3Mo(η6-C6Me3H 2)]Ga(C6Me3H2)2 and [(CO)3Mo(η6-C6Me3H 2)]2Ga(C6Me3H2). The first examples of arene-group 6 metal tricarbonyl complexes which have gallium-containing substituents bonded to an arene ring, [(CO)3MoMes]GaMes2, [(CO)3MoMes]2GaMes, [(CO)3MoMes]-GaCl2·1/2DME, and [(CO)3MoMes]2GaCl·1/2DME (Mes = C6Me3H2 = mesityl), have been prepared and characterized by elemental analyses, IR and 1H NMR spectroscopy, and reactions with hydrogen chloride. X-ray structural studies have defined the nature of [(CO)3MoMes]GaMes2 and [(CO)3MoMeS]2GaMes in the solid state. Both complexes can be described as GaMes3 molecules with either one or two Mo(CO)3 units bonded in η6 fashion to mesityl rings. The yellow crystal of [(CO)3MoMes]GaMes2 that cocrystallized with a benzene solvent molecule consisted of discrete molecules with no abnormally close intermolecular interactions. The compound crystallized in the triclinic space group P1 with a = 9.171 (1) A?, b = 12.702 (2) A?, c = 14.649 (3) A?, α = 81.16 (2)°, β = 79.03 (1)°, γ = 109.82 (1)°, V = 1531.3 (5) A?3, and Z = 2 (formula units). The structure was refined to R(F) = 4.7% for 2148 reflections. The yellow compound [(CO)3MoMes]2GaMes crystallized in the orthorhombic space group Pbcn with a = 17.587 (3) A?, b = 12.186 (2) A?, c = 15.497 (3) A?, V = 3321.4 (11) A?3, and Z = 4 (formula units). This structure refined to R(F) = 4.6% for 1254 reflections. These new arene complexes react with anhydrous HCl in either DME or THF solution. The gallium-mesityl carbon bond to the uncomplexed mesityl ring was preferentially cleaved.
