Abstract : The reaction of [Fe2(μ-S(CH2)3S)(CO) 6] with an excess of 1,3-dimethylimidazol-2-ylidene (LMe) affords the mono- and disubstituted species [Fe2(μ-S(CH 2)3S)-(CO)5(LMe)] (1) and (Fe 2(μ-S(CH2)3(CO)4(L Me)2) respectively. The structures of 1 and 2 have been determined by X-ray crystallography. © 2005 American Chemical Society.
