| Abstract: | Two routes to 1,1-dithiolate complexes cis-Ru(CO)2(S2X)2] X = NMe2, OEt, PPh2, P(OEt)2] are presented. From the reaction of NH4S2P(OEt)2 with the ruthenium(II) complex generated upon reduction of RuCl3.3H2O by CO in 2-methoxyethanol, along with the expected mononuclear product, cis-Ru(CO)2{η2-S2P(OEt)2}2], binuclear Ru(CO){η2-S2P(OEt)2} {μ,η1,η2-S2P(OEt)2}]2 was also produced. The latter has been crystallographically characterized and shows a trans-arrangement of carbonyls and cis-arrangement of terminal and bridging dithiolate ligands. |
