Organometallic rhenium(iii) chalcogenide clusters: coordination of N-heterocyclic carbenes†
Abstract
The preparation of rhenium based octahedral clusters containing N-heterocyclic carbenes is described. These represent the first examples of [M6(μ3-Q)8]n+ or [M6(μ3-X)8]n+ clusters to contain a carbene ligand of any type (NHC, Fischer or Schrock). Surprisingly, the NHC ligands attenuate their luminescent properties.
