Abstract
Insertion of GeCl 2 into the Au–Cl bonds of [(AuCl) 2 (dppm)] or [(AuCl) 2 (dppe)] (dppm = Ph 2 PCH 2 PPh 2 and dppe = Ph 2 PCH 2 CH 2 PPh 2 ) leads to the formation of bis(trichlorogermyl) complexes [Au 2 (dppm/e) 2 ] 2+ [Au(GeCl 3 ) 2 ] 2 - , of which the dppm complex undergoes slow decomposition in solution to give [Au 2 (dppm) 2 ][Au(GeCl 3 ) 3 ], where the gold atom of the dianion is co-ordinated solely to three germanium atoms.Keywords
