The preparation and structure of [Co3(η-C5H5)3(µ3-CNC6H11)(µ3-S)]; the first example of an organoisocyanide as a triply bridging, two-electron donor ligand

Abstract

The reaction of [Co(η-C₅H₅)(Co)(PPh₃)] with RNCS in refluxing benzene gives [Co(η-C₅H₅)(PPh₃)(η²-PhNCS-C,S)] and [Co₃(η-C₅H₅)₃(µ₃-CNR)(µ₃-S)](2)(R = Me, C₆H₁₁, or Ph); the structure of (2; R = C₆H₁₁) has been determined by an X-ray diffraction study.
