Homo (Au2)- and heterodinuclear coinage metal complexes (AuAg) ligated by a six-membered Janus-type ditopic N-heterocyclic carbene (NHC) have been prepared by deprotonation of aNHC (abnormal NHC) gold complex followed by complexation. The two ditopic NHC coinage metal complexes were structurally characterized by single crystal X-ray diffraction. The carbene character for the C2 carbon and C5 carbon of the ditopic NHC ligand in 3 and 4 was confirmed by the NMR and structural data.
