Synthesis and characterization of two new classes of ruthenium(III)-sulfoxide complexes with nitrogen donor ligands (L): Na[trans-RuCl4(R2SO)(L)] and mer, cis-RuCl3(R2SO)(R2SO)(L). The crystal structure of Na[trans-RuCl4(DMSO)(NH3)] · 2DMSO, Na[trans-RuCl4(DMSO)(Im)] · H2O, Me2CO (Im = imidazole) and mer, cis-RuCl3(DMSO)(DMSO)(NH3)

respectively. In 5a and 5b, the DMSO ligand is S-bonded to Ru, with RuS bond distances (trans to N) of 2.2797(7) and 2.2956(6) A, respectively, while in 6a, one DMSO, trans to N, is S-bonded (RuS, 2.2714(6) A), and the other, trans to Cl, is O-bonded (RuO, 2.070(2) A). The RuCl bond distance, trans to O, is 2.3207(7) A. The RuCl bond distances, trans to Cl, are similar in all three compounds averaging 2
摘要本文报道了两类新型的含氮配体(L)的氯化物-亚砜-Ru(III)衍生物的合成:Na [反式RuCl4(R2SO)(L)]和mer,cis- RuCl3(R2SO)(R2SO)(L)。还描述了它们在固态(IR)和溶液(NMR,UVVis)中的光谱表征。在水溶液中进行的络合物的循环伏安法在每种情况下均显示出单电子且相当快速的Ru(III)/ Ru(II)电子转移。所观察到的形式势比其他Ru(III)络合物所报告的形式势要积极得多。净电荷以及DMSO的π酸性是导致此行为的因素。Na [反式RuCl4(DMSO)(NH3)]·2DMSO(5a),Na [反式RuCl4(DMSO)(Im)]·H2O,Me2CO 5b和mer的晶体结构,通过三维X射线分析确定了顺式RuCl3(DMSO)(DMSO)(NH3)(6a)。晶体数据为:a = 9.578(2),b = 12.480(2),c = 9.594(6)A,α=
