Cobalt/Mercury Carbide Clusters Based on Trigonal-Prismatic or Octahedral Co6C Skeletons − X-ray Crystal Structure of (NEt4)2[Co6C(CO)12{HgW(CO)3Cp}2]

Abstract

The anionic transition metal clusters (NEt4)[Co6C(CO)x{HgM}] [M = W(CO)3Cp, Mo(CO)3Cp, Fe(CO)2Cp, Co(CO)4, Mn(CO)5] (x = 13 or 15) have been obtained by reaction of the corresponding octahedral (x = 13) or trigonal‐prismatic (x = 15) cobalt carbido carbonyl clusters with the mercury derivatives ClHgM. Metal skeleton rearrangements and some redox processes have been found to be induced by varying both the temperature and the solvent, resulting in new compounds containing tetra‐ or hexacoordinated mercury atoms.
