Carbide complexes as π-acceptor ligands.

ABSTRACT: The π-accepting character of a terminal carbide complex acting as a ligand is demonstrated experimentally and corroborates earlier theoretical predictions. As a result, coordination of a terminal ruthenium carbide complex to electron-rich metal centres is shown to provide a facile and versatile route to carbide-bridged heterometallic complexes. Synthesis, reactivity, spectroscopic and structural characterization are reported for heterobimetallic systems with auxiliary metals from groups 9-11: Rh(i), Ir(i), Pd(ii), Pt(ii), Ag(i), and Au(i) coordinated by [Ru(C)Cl₂(PCy₃)₂] (RuC). This encompasses the first example of a homoleptic carbide-ligated transition metal complex: [{(Cy₃P)₂Cl₂RuC}₂Au]⁺
