The dithia[3.3]paracyclophane-bridged bimetallic ruthenium alkynyl and vinyl complexes Cp*(dppe)RuC≡C}2(μ-dithia[3.3]paracyclophane) (8) and (PMe3)3(CO)ClRuCH═CH}2(μ-dithia[3.3]paracyclophane) (9) have been prepared and, in the case of 8, structurally characterized. Compounds 8 and 9 each undergo two consecutive one-electron-oxidation processes, with supporting investigations conducted using IR and
双硫[3.3]对环烷桥联的双金属钌炔基和乙烯基络合物Cp *(dppe)RuC≡C} 2(μ-二硫代[3.3]对环环烯)(8)和(PMe 3)3(CO)ClRuCH═CH }已准备好2(μ-dithia[3.3] paracyclophane)(9),在8的情况下,对其进行结构表征。化合物8和9各自经历两个连续的单电子氧化过程,并使用IR和UV / vis /近红外光谱电化学方法进行了辅助研究,建立了在8和9中双硫[3.3]对环环烷桥单元的氧化还原-非清纯特性。9。[ 8 ] +和[ 9 ] +在近红外区域均表现出多个跃迁,借助DFT计算,这些跃迁已被指定为MLCT和内配体跃迁的组合,以及涉及环烷骨架中供体硫原子的跃迁。位于桥接环烷的二乙炔基或二乙烯基亚苯基部分的部分占据的轨道。
