When Au(I) is provided with endocyclic soft thioether or endocyclic hard amine, endocyclic borderline imine and exocyclic hard amine coordination sites, the softer borderline endocyclic imine coordination site is favored. This is demonstrated by the synth

We have synthesized the gold complexes [Au(C6F5)(2-amt)], 1, [Au(C6F5)(2-amt)], 2, and [Au(2-amt)(PPh3)]{CF3SO3), 3, where 2-amt = 2-aminothiazoline (2-amino-4,5-dihydrothiazole) by displacement of labile ligands from corresponding gold(III) and gold(I) precursors. The reaction of 2-amt with [Au(acac)(PPh3)] evolves to an unprecedented ring-opening reaction to give the new ligand (2-cyanamide)ethylthiolate, stabilized as a dinuclear gold(I) coordination derivative, [(AuPPh3)2(μ-SCH2CH2N-CN)], 4. The molecular structure of complexes 1 and 4 has been confirmed by X-ray diffraction studies. Complex 4 displays short gold-gold distances of 3.0821(3), 3.17618(19), and 3.2867(2) A?(three different molecules in two different crystal forms) and secondary sulfur-gold or nitrogen-gold bonds. Complexes 3 and 4 luminesce intensely in the solid state at low temperature.
