Unexpected formation of the novel mixed μ-oxo, μ-sulfido, bis(μ-thiolato) compound [Mo(IV)2Cp2(μ-O)(μ-S)(μ-SMe)2]
Résumé
A novel example of C-S bond cleavage in a dimolybdenum derivative leads to the formation of the quadruply bridged compound [Mo(IV)2Cp2(μ-O)(μ-S)(μ-SMe)2]. This μ-oxo species is formed by reaction of the chloro-bridged complex [Mo(III)2Cp2(μ-Cl)(μ-SMe)3] with PhCCLi and subsequent hydration at the dimolybdenum site. The Mo-Mo bond length of 2.4900(3)Å in [Mo2Cp2(μ-O)(μ-S)(μ-SMe)2] is unusually short. © 2001 Elsevier Science B.V.
