Abstract

Abstract : The first tetrametallagermoxane [(Cp*Ru(CO)2 Ge)4 (μ-O)6 ], with an adamantanoid cage structure, has been synthesized and structurally characterized with an exo -{Cp*Ru(CO)2 } fragment in each germanium atom. Abstract : In an attempt to synthesize a zero valent germanium compound, we have carried out the reaction of [(Cp*RuCO)(GeCl2 )]2, 1 with potassium metal that led to the formation of a metallagermoxane [(Cp*Ru(CO)2 Ge)4 (μ-O)6 ], 2 . Compound2 is the first example of a tetrametallagermoxane with an exo -{Cp*Ru(CO)2 } fragment. DFT calculations were used to examine the key intermediates associated with the formation of2 .
