Synthesis and molecular geometry of novel di- and tri-nuclear iron complexes resulting from the interaction of [Fe2(CO)9] with R–NSN–R (R = t-butyl or p-tolyl); X-ray crystal structures of [Fe2(CO)6{RNC(O)S}] and [Fe3(CO)9(RNS)S

Abstract

The reaction of [Fe2(CO)9] with RNSNR (R = But or p-tolyl) leads to a breakdown of the diimidosulphur ligand resulting in the formation of [Fe2(CO)6(RNS)](R = But), [Fe3(CO)9S2], [Fe3(CO)9(RNS)S](R =p-tolyl), and [Fe2(CO)6{RNC(O)S}](R =p-tolyl or But) which involves the as yet unknown insertion of CO into a N–S bond, and [Fe3(CO)9(RNS)S](R = But) which has the novel prismane type structure.
