In the reaction of (η5-pentamethylcyclopentadienyl)gallium (Cp*Ga) with Ni(COD)2 (COD = 1,5-cyclooctadiene) and NorM(CO)4 (Nor = norbornadiene; M = Cr, Mo) the complexes Ni(Cp*Ga)4 (1) and cis-M(Cp*Ga)2(CO)4 (M = Cr (2), Mo (3)), respectively, were obtained. Compounds 1−3 were characterized by NMR and IR data and by elemental analysis. In addition, an X-ray crystal structure analysis was performed on complexes 1 and 3. Cis-orientation of the Cp*Ga ligands is made possible by deviation of the Cp*centroid−Ga−M vector from linearity. 1 is the first homoleptic complex with Cp*Ga as ligand.
