AbstractThe first xylene-bridged bis(N-heterocyclic carbene) (bis(NHC))-ligated CCC-pincer rare-earth metal dibromides (PBNHC)LnBr(2)(THF) (PBNHC = 2,6-(2,4,6-Me(3)C(6)H(2)NCHCHNCCH(2))(2)C(6)H(3); 1: Ln = Sc; 2: Ln = Lu; 3: Lu = Sm) were prepared by in situ treatment of a THF suspension of 2,6-bis(1-mesitylimidazolium methyl)-1-bromobenzene dibromides ((PB-NHC-Br) center dot 2HBr) and lanthanide trichlorides (LnCl(3)) with dropwise addition of nBuLi at room temperature. The overall molecular structure of these complexes is an isostructrual monomer of a THF solvate. The monoanionic xylene-bridged bis(NHC)s bond to the central metal as a tridentate CCC-pincer moiety in a kappa C:kappa C:kappa C' mode, which, in combination with the two trans-located bromo units, generates a twisted tetragonal-bipyramidal geometry.
