Can Acetylenedithiolate Act as a Tetradentate Bridging Ligand?

Abstract

Tetradentate and ambidentate: Because the four-atom acetylenedithiolate has donor electron density on all sides of the dianion, it can link and electronically couple different metal ions. The bend-back angles of the sulfur atoms in the η2-C,C′-acetylenedithiolate complex [Tp′W(CO)2(η2-C2S2)]− are sufficiently flexible to allow for a chelation of both sulfur donors to the {(η5-C5H5)Ru(PPh3)} fragment (see structure).
