Removal of one chloride ligand from the aminocarbene fac-[(PNP)RuCl₂(C{N(H)Ph}{CHiPh})] in THF followed by treatment with phenylacetylene yields the ruthenium (II) complex mer-[(PNP)RuCl{C-C(H)Ph}(C{N(H)Ph)}{CH₂Ph})] PF₆ (4). Complex 4 represents the first example of a transition metal complex with the simultaneous coordination of vinylidene and carbene ligands.
