Lewis acid-base adducts of pentamethylcyclopentadienylgallium with trivalent group 13-element compounds

In the reaction of (eta (5)-pentamethylcylopentadienyl)gallium (Cp*Ga) with B(CsF5)(3), (GaBu3)-Bu-t, and Cp*GaX2 (X = Cl, I) the new complexes Cp*GaB(C6F5)(3), 1, Cp*(GaGaBu3)-Bu-t, 2, and Cp*GaGa(X)(2)Cp* (X = Cl, 3; I, 4), respectively, were obtained. Alternatively, complex 3 was formed in the reaction of Cp*Ga with InCl. Compounds 1-4 were characterized by analytical and spectroscopic methods. In addition, X-ray crystal structure analyses of 1, 3, and 4 were performed.
