The complexes Au2Cl2(P-P) with P-P = biphep (2,2′-bis(diphenylphosphino)-1,1′-biphenyl), binap (2,2′-bis(diphenylphosphino)-1,1′-binaphthyl) and xantphos (9,9′-dimethyl-4,5-bis(diphenyl-phosphino)xanthene), were prepared and characterized by elemental analysis and ESI-MS. The solid compounds show a r.t. phosphorescence. While the binap complex emits from an intraligand (IL) triplet, the luminescence of the biphep complex originates from a metal-centered (MC) triplet which is presumably lowered by gold-gold interaction. The xantphos complex displays a dual phosphorescence. In this case, the emitting triplets are of the IL and MC type.

By employing chiral precursors, a new class of chiral gold(I)-sulfido clusters with unique structures has been constructed. Interestingly, pure enantiomers of the precursors are found to self-Assemble into chiral hexa-and decanuclear clusters sequentially, while a racemic mixture of them has resulted in heterochiral self-sorting of an achiral meso decanuclear cluster. Chirality has determined not only the symmetry and structures but also the photophysical behaviors of these clusters. The racemic mixture of decanuclear clusters undergoes rearrangement and heterochiral self-sorting to give a meso decanuclear cluster. The thermodynamic-driven heterochiral self-sorting of gold(I) clusters provides a means to develop controlled self-Assembly that may be of relevance to the understanding of chirality in nature.

The chemistry of gold(I) with the ligand binap = 2,2′- bis(diphenylphosphino)-1,1′-binaphthyl is reported. Reaction of [Au 2Cl2(μ-binap)] with silver trifluoroacetate gave the corresponding complex [Au2(O2CCF3) 2(μ-binap)], and crystallization in the presence of excess silver trifluoroacetate gave the unusual syndiotactic polymeric complex [{Au 2Ag2(μ-O2CCF3) 4(μ-binap)}n], which contains both Au·· ·Ag and Ag···Ag metallophilic bonds. The trifluoroacetate ligands in [Au2(O2CCF3) 2(μ-binap)] can be replaced by nitrogen or phosphorus donor ligands to give complexes [Au2(κ1-4,4′- bipyridine)2(μ-binap)](CF3CO2)2 or meso-[Au2(μ-binap)2](CF3CO 2)2.
