Abstract

International audienceThe paramagnetic μ-amidato species[Mo2Cp2(μ-MeCONH)(μ-SMe)3]BF 4 2a+ (Cp = η-C5H5) is formed exclusively when the compound[Mo2Cp2(MeCN)2(μ-SMe) 3]BF4 1a in powder form is kept in air, whereas the same starting complex in solution gives a mixture of the μ-amidato species and the μ-oxo complex[Mo2Cp2(μ-O)(μ-SMe)3]BF 4 3. The oxo complex is formed quantitatively on warming[Mo2Cp2(μ-Cl)(μ-SMe)3]BF 4 in water. The reduction of2a+ by NaBH4 in CH3CN affords the molecular product[Mo2Cp2(μ-MeCONH)(μ-SMe)3] 2a which has been characterised by X-ray analysis
