Abstract

Abstract A novel example of CS bond cleavage in a dimolybdenum derivative leads to the formation of the quadruply bridged compound [Mo(IV) 2Cp 2(μ-O)(μ-S)(μ-SMe) 2]. This μ-oxo species is formed by reaction of the chloro-bridged complex [Mo(III) 2Cp 2(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 [Mo 2Cp 2(μ-O)(μ-S)(μ-SMe) 2] is unusually short.
