Abstract

The X-ray structural study of the reaction product of equimolar amounts of [Au3Cu2(C2Ph)6]. [{Au(C2Ph)} n ], and [Ag(C2Ph)} n ] revealed two bimetallic anionic [N(PPh3)2] + [Au3Ag2(C2Ph)6]− and [N(PPh3)2]+[Au3Cu2 (C2 Pg)6] — clusters co-crystallized in one asymmetric unit. Each cluster has trigonal bipyramidal geometry with three gold atoms occupying equatorial planes and two silver or copper atoms in the apical positions. Our earlier conclusion based upon spectroscopic characterization describing the product of be above reaction as trimetallic cluster containing three coinage-metals with an overall composition [Au3CuAg(C2Ph)6]−, was erroneous.
