摘要我们在此报告了十三种铑(III)混合二亚胺配体配合物的首次常规,高纯度,高收率合成,其中九种是新的,四种是已知的并作为对照。我们使用双三氟甲磺酸酯中间体是因为不稳定的三氟甲磺酸酯配体很容易被传入的二亚胺配体取代,并允许这些合成在相对温和的反应条件下以高收率(84-97%)进行。产物的纯度通过元素分析和1 H NMR确定。对化合物进行了电子表征,我们研究了各种给电子和吸电子取代基对配合物基态和激发态性质的影响。我们观察到在2上的替换

Electrochemistry shows irreversible two-electron reduction of Rh(III) to Rh(I) and a concomitant loss of one bipyridine ligand; this is followed by reversible one-electron reduction of the remaining 2,2'-bipyridine ligand. The electronic characterizations of these complexes are consistent with significant delocalization of the sulfur electron density onto the empty metal d orbitals. The 1,1'-dithiolate

The preparation, spectroscopic and electrochemical properties of the cyclometallated complex [Rh(bipy)2(ppy)][PF6]2 are reported. The crystal and molecular structure of the complex are reported; the cation exhibits a six-fold disorder and closely resembles the [Rh(bipy)3]3+ cation.
