A tritopic carbanionic N-heterocyclic dicarbene and its homo- and heterometallic coinage metal complexes†
Abstract
Homo (Au3)- and heterotrinuclear coinage metal complexes (Au2Ag and Au2Cu) ligated by the first tritopic carbanionic N-heterocyclic carbene (NHC) have been prepared by deprotonation of ditopic NHC digold complexes and structurally characterized by single-crystal X-ray diffraction.
