New studies on the chemical oxidation of (bisη5-cyclopentadienyl)dithiolatemolybdenum(IV) complexes. Crystal structures of [Mo(η5-C5H5)2S(C6H4-o-SC6H5)][BF4] and [Mo(η5-C5H5)2(SC6H5)2]

A new pattern on the reactivity of bis(η5-cyclopentadienyl)dithiolatemolybdenum(IV) metalloligands was found upon study of several chemical reactions involving the redox behaviour of these compounds. Chemical oxidants, such as Ag+ and NO+, led to very different monochelate and binuclear final products. The molecular structure of the new compound which contains the metalloring cation [C6H5)]+ was characterised by single-crystal X-ray diffraction, and for comparison, also the molecular structure of the parent compound [Mo(η5-C5H5)2(SPh)2] is also presented and discussed.
