title: A step forward in gold-silver metallophilicity. An AuAg4 moiety with a square pyramidal arrangement.
abstract: By reaction of the Lewis base NBu4[Au(3,5-C6F3Cl2)2] and AgCF3COO in the presence of NBu4CF3COO the heterometallic compound (NBu4)2[Au(3,5-C6F3Cl22Ag4(CF3COO)5] (2) is obtained. The structure displays an unprecendented square pyramidal AuAg4 arrangement built up through four AuAg closed-shell interactions and two Au-C-Ag 3c-2e- bridges.
