Reaction of the unsaturated anion [Re 3H 4(CO) 10] - with mercaptans. Synthesis and X-ray Characterization of the anion [ Re 3H 3 (CO) 9(μ 3-SBu t)]

The novel anion [Re 3H 3(CO) 9(μ 3-SBu t)] -, obtained by reaction of [Re 3H 4(CO) 10] - with t-butyl mercaptan, has been characterized by IR, NMR and X-ray diffraction studies. It contains an equilateral Re 3 triangle (mean ReRe 3.091 Å), with nine terminal carbonyl groups, three for each metal atom, and a triply-bridging thiolate ligand (mean ReS 2.393 Å). The three hydrides are bridging on the edges of the triangle of metal atoms. © 1982.
