Synthesis, structure, luminescence, and Raman-determined excited state distortions of a trinuclear gold(I) phosphine thiolate complex, S. D. Hanna, S. I. Khan, J. I. Zink, Inorg. Chem. 1996, 35, 5813. [Pg.85]

Gold(I) thiolate complexes have different stoichiometries, the neutral [Au(SR)(PR3)] complexes are very numerous and have been synthesized for a great variety of thiolate and tertiary phosphine ligands. The phosphine is usually PPh3 (otherwise state) and the substituent R in the thiolate moiety can be Me (PMe3),2779 Ph (PR 3 PPh3, TPA),2780-2784 2,4,6-C6H2R23 (R2 = Me,... [Pg.1058]

The described reaction proceeds slowly for aryl-thiolate DNICs and is fast for alkyl-thiolate complexes. Trapping of the elemental sulfur atoms by phosphine inhibits oxidation [137]. The fate of the sulfide ligands in reactions of biological iron-sulfur clusters with NO remains unknown, although analogically it is expected that sulfur by-products must be sequestered from the vicinity of the iron atoms in order for the DNICs to remain stable. It was shown that the cluster reassembly... [Pg.65]
