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 (C₂Ph)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 speclroscopic characterization describing the product of the above reaction as trimetallic cluster containing three coinage-metals with an overall composition [Au₃CuAg(C₂Ph)₆]^- was erroneous.
