A Novel Au12 Supramolecule Composed of Two-, Three-, and Four-coordinated Au(I) Centers Constructed on the S3 Scaffolding

A novel Au12 supramolecule (12) composed of two-, three-, and four-coordinated Au(I) centers was constructed on the S3 scaffolding (trithiocyanurate, S3C3N33-). 12 can be regarded as a tetramer of the Au3 unit, [AuP(3-CF3–C6H4)3]3(S3C3N3) by losing four P(3-CF3–C6H4)3 ligands upon tetramerization. A congener of the monomer unit [AuP(2-py)(C6H5)2]3 (S3C3N3) (2) was also synthesized; X-ray study on 2 revealed in turn a monomer structure.
