Abstract

The reaction of [Cp+Fe(CO)2]2 (Cp+= eta5-C5Me4Et) with equimolar amounts of As4S4 in boiling toluene gives Cp+2Fe2As2S2 (1) and Cp2+Fe2As2S3 (2). Both complexes form with two equivalents of Cr(CO)5THF the bisadducts Cp+2Fe2As2S2.2Cr(CO)5 (3) and Cp+2Fe2As2S3.2Cr(CO)5 (4), respectively. The Cr(CO)5 fragments are bound to the As atoms. X-ray diffraction analyses have been carried out for 1 and 4. ...
