摘要：

In the reaction of (eta(5)-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.
