title: Synthesis of novel chiral Cu or Ag/S,N cluster complexes and absolute stereostructures as determined by x-ray crystallography.
abstract: Novel chiral copper(I) and silver(I) metal complexes were synthesized from the reaction of chiral 1,3-thiazolidine-2-thione ligand with CuCl and AgOAc in dichloromethane in the presence of Et(3)N and DMAP at room temperature. Their unique crystal structures were determined by X-ray analysis. Four Cu(I) atoms and four 1,3-thiazolidine-2-thione ligands form a butterfly-type metal cluster. Six Ag(I) atoms and six 1,3-thiazolidine-2-thione ligands form another butterfly-type cluster.
