摘要

Treatment of the trigonal-bipyramidal ruthenium(IV)-thiolate complex, [Ru(SMes)(4)(MeCN)] (Mes=2,4,6-trimethylphenyl, 1), with an anhydrous diethyl ether solution of hydrogen chloride in THF afforded [Ru(SMes)(3)Cl(MeCN)] (2), whereas interaction of 1 with [Et4N]Cl in THF gave an anionic ruthenium(IV)-thiolate complex, [Et4N][Ru(SMes)(4)Cl] (3). Reaction of 1 with one equivalent of substituted pyridines in dichloromethane gave the corresponding pyridine-coordinated ruthenium(IV)-thiolate complexes, [Ru(SMes)(4)(R-py)] (R=4-Et, 4; 4-Bu-t, 5; 3,5-Me-2, 6), while reaction of 1 with 0.5 equiv. of 4,4'-bipy (4,4'-bipy=4,4'-bipyridine) in dichloromethane resulted in the formation of a dinuclear ruthenium(IV)-thiolate complex [{Ru(SMes)(4)}(2)(-4,4'-bipy)] (7). Complexes 2-7 have been spectroscopically characterized along with their electrochemical analyses, and their structures have been determined by single-crystal X-ray diffraction.
