The very stable selenium‐bridged gold complexes [Au 10 Se 4 (dppm) 4 ]Br 2 and [Au 18 Se 8 (dppe) 6 ]Cl 2 were obtained by the reaction of gold halide–phosphane complexes [(AuX) 2 (Ph 2 P(CH 2 ) n PPh 2 )] (X=halide; n =1, 2) with silylated selenium derivatives. With the help of electrospray/ionization it was possible to promote the cation [Au 18 Se 8 (dppe) 6 ] 2+ (see structure; m / z 6568 (!)) nearly fragment‐free into the gas phase. dppm=bis(diphenylphosphanyl)methane, dppe=bis(diphenylphosphanyl)ethane.
