The first metal N-heterocyclic carbene complexes derived from a cyclic tetraimidazolium salt show a remarkable versatility of ligand conformation and coordination geometry. With PdII, a mononuclear square-planar complex is obtained, but with CuI and AgI, an unprecedented dinuclear motif with a short metal–metal interaction is observed (see structure; N blue, C white ellipsoids, H white circles).
