Ru(η6-cot)(η2-dmfm)2 (1; cot = 1,3,5-cyclooctatriene, dmfm = dimethyl fumarate) reacted with p-quinones to give novel p-quinone-coordinated ruthenium(0) complexes, Ru(η6-cot)(p-quinone) (2), in good to high yields via the replacement of two dimethyl fumarates by p-quinones. The reaction of 1 with p-biquinone gave a novel bimetallic zerovalent complex {Ru(η6-cot)}2(p-biquinone) (3), in which p-biquinone coordinates to two isolated Ru(cot) moieties with a unique mode and the two Ru(cot) groups are located at endo positions. Complexes 2 and 3 have either p-quinone or p-biquinone as π-acceptor ligands. The structures of complexes Ru(η6-cot)(2,6-dimethoxy-p-quinone) (2f) and 3 were determined by X-ray crystallography.
