Abstract

A reaction of the triple cubane-type organometallic polyoxomolybdate cluster, [(Cp * Rh)₄Mo₄O₁₆] · 2H₂O (1 · 2H₂O), with 1,2-benzenedithiol gives a 1,2-benzenedithiolate-bridged dinuclear complex, [(Cp * Rh)₂(μ(S)-1,2-C₆H₄S₂-S,S′)₂] (2), and another dinuclear complex, [(Cp * Rh)₂(μ(S)-1,2-C₆H₄S₂-S,S′)(μ(S)-1,2-C₆H₄S(SO₂)-S,S′)] (3), both of which are characterized by the single-crystal X-ray diffraction method. The former complex, 2, is also obtained from a reaction of [(Cp * RhCl)₂(μ-Cl)₂] with 1,2-benzenedithiol in the presence of NaOCH₃, and the latter, 3, from oxygenation of 2 with t-BuOOH. The ¹H NMR study in CD₂Cl₂ indicates that complex 2 changes gradually to a coordinatively unsaturated mononuclear complex, [Cp * Rh(1,2-C₆H₄S₂-S,S′)] (4). An analogous mononuclear iridium(III) complex, [Cp * Ir(1,2-C₆H₄S₂-S,S′)] (5), is also prepared and characterized by X-ray structural analysis.
