摘要：

A mixture of [HB(3,5-(CF3)(2)Pz)(3)]Ag(eta(2)-toluene) and [(Me)(2)ATI]GeCl in CH2Cl2, rather than undergoing metathesis, formed a 1:1 adduct [HB(3,5-(CF3)(2)Pz)(3)]Ag<--GeCl[(Me)(2)ATI] (1, where [HB(3,5-(CF3)(2)Pz)(3)] = hydrotris(3,5-bis(trifluoromethyl)pyrazolyl)borate and [(Me)(2)ATI] = N-methyl-2-(methylamino)troponiminate) featuring a silver-germanium bond. Solutions of 1 (in CH2Cl2 or toluene) did not precipitate AgCl even after several days. However, it easily underwent metathesis with CF3SO3Ag, leading to the chloride-free product [HB(3,5-(CF3)(2)Pz)(3)]Ag<--Ge-(OSO2CF3)[(Me)(2)ATI] (2). Compounds 1 and 2 were characterized by X-ray crystallography. The Ag-Ge bond distances of 1 and 2 are 2.4215(9) and 2.4116(10) Angstrom, respectively.
