Syntheses and crystal structures of neutral tetrairon complexes with the unique SCPPh2S ligand†
Abstract
The novel reactions of cluster salts [(μ-RS)Fe2(CO)6(μ4-CS2)Fe2(CO)6][Et3NH] with Ph2PCl, via the insertion of the PPh2 group into an activated C–S bond, afford the unprecedented tetrairon complexes with the unique SCPPh2S
