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.
