Boat-shaped Co6 carbonyl cluster derivatives containing a semi-interstitial P atom and bridging thiolate or heterocyclic phosphido ligands

Abstract

Reactions of MeSPCl₂, EtSPCl₂ and Cl[graphic omitted], respectively with Co₂(CO)₈ in the presence of zinc powder give the Co₆ clusters [Co₆(µ₆-P)(µ-SMe)₃(CO)₁₂]1, [Co₆(µ₆-P)(µ-SEt)₃(CO)₁₂]2 and [Co₆(µ₆-P)(µ₄-SCH₂CH₂S)(µ-µ-[graphic omitted])(CO)₁₂]3 respectively; in 1 six Co atoms form a boat-shaped array consisting of a basal square of four cobalt atoms with two opposite edges bridged by two apical Co atoms, with the metal arrangement surrounding a semi-interstitial P atom, and with two µ-SMe ligands bridging underneath the basal square and another bridging µ-SMe side-linked to the basal square.
