A new μ(4)-bpym-bridged dimer of an oxoacetao-triruthenium complex with carbonyl, [{Ru(3)O(CH(3)COO)(5)(CO)(py)}(2)(μ(4)-bpym)], was synthesized. The complex possesses two stable mixed-valence states associated with Ru(3)(III,III,II)/Ru(3)(III,II,II) and Ru(3)(III,III,III)/Ru(3)(III,III,II). The IR-spectroelectrochemistry reveals ν(CO) spectra in five oxidation states, Ru(3)(III,III,III)-Ru(3)(III,III,III) to Ru(3)(III,II,II)-Ru(3)(III,II,II) and both the mixed-valence states show a spectrum indicating medium interaction between the Ru(3) units.
一种新的μ(4)-bpym 桥联双三核铼配合物，具有羰基，[{Ru(3)O(CH(3)COO)(5)(CO)(py)}(2)(μ(4)-bpym)]，被合成出来。该配合物具有两个稳定的混合价态，与 Ru(3)(III,III,II)/Ru(3)(III,II,II) 和 Ru(3)(III,III,III)/Ru(3)(III,III,II)有关。IR 光谱电化学揭示了五个氧化态的 ν(CO)光谱，Ru(3)(III,III,III)-Ru(3)(III,III,III)到 Ru(3)(III,II,II)-Ru(3)(III,II,II)，并且两种混合价态都显示出表明 Ru(3)单元之间中等相互作用的光谱。
