Janus-type dianionic bis(maloNHC) (1) was synthesized and characterized by NMR spectroscopy. The utility
of this extended biscarbene for the construction of homobimetallic
systems has been demonstrated by its coordination to two coinage metals.
The resulting zwitterionic metal complexes of the type [(Ph3P)M(1)M(PPh3)] (M = Au, Ag) have been fully
characterized. The X-ray crystallography shows that the new ligand
positions the two metal centers at a distance of 24.2 Å, the
longest distance reported to date for any related NHC ligand.
