摘要
The very stable selenium-bridged gold complexes [Au10Se4(dppm)4]Br2 and [Au18Se8(dppe)6]Cl2 were obtained by the reaction of gold halide- phosphane complexes [(AuX)2(Ph2P(CH2),1PPh2)] (X = halide; n = 1, 2) with silylated selenium derivatives. With the help of electrospray/ionization it was possible to promote the cation [Au18Se8(dppe)6]2+ (see structure; m/z 6568 (!)) nearly fragment-free into the gas phase, dppm=bis(diphenylphosphanyl)methane, dppe = bis(diphenylphosphanyl)ethane.
