A luminescent gold(i)–copper(i) cluster with unprecedented carbon-centered trigonal prismatic hexagold†
Abstract
An unprecedented trigonal prismatic (μ6-C)Au6 structure has been found in a novel gold(I)–copper(I) cluster with a hypercoordinated carbon, [CAu6Cu2(dppy)6](BF4)4; the incorporation of copper ions enhances the rigidity and integrity of the cluster and turns on the bright red solution luminescence.
