Cluster chemistry. Application of gold–oxonium reagents to the synthesis of poly-gold mixed-metal clusters: preparation and X-ray crystal structure of [Au3CoRu3(CO)12(PPh3)3], containing a bicapped trigonal-bipyramidal metal cluster

Abstract

Reaction Between [{Au(PPh₃)₂}O][BF₄] and [HCoRu₃(CO)₁₃] or [CoRu₃(CO)₁₃]^– gives good yields of the title cluster which has been shown by an X-ray crystal structure analysis to have a seven-metal-atom skeleton, in which two gold atoms cap adjacent AuCoRu and AuRu₂ faces of the trigonal bipyramidal AuCoRu₃ core.
