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)3Cl(MeCN)] (2), whereas interaction of1with [Et4N]Cl in THF gave an anionic ruthenium(IV)–thiolate complex, [Et4N][Ru(SMes)4Cl] (3). Reaction of1with 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-tBu,5; 3,5-Me2,6), while reaction of1with 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(μ-4,4’-bipy)] (7). Complexes2–7have been spectroscopically characterized along with their electrochemical analyses, and their structures have been determined by single-crystal X-ray diffraction. [ABSTRACT FROM AUTHOR] |
