| Abstract: | Heating cis-Ru(S2CNMe2)2(CO)2] and Ru3(CO)12] in xylene affords octanuclear Ru8(μ5-S)2(μ4-S)(μ3-S)(μ-CNMe2)2(μ-CO)(CO)15] resulting from the double carbon-sulfur bond cleavage of two dithiocarbamate ligands. The structure consists of a tri-edge-bridged square of ruthenium atoms with a further ruthenium atom being bound only to the central bridging atom. Studies suggest that it may be formed via the pentanuclear intermediate Ru5(μ4-S)2(μ-CNMe2)2(CO)11] which is formed in trace amounts. |
