Abstract
The seminal isolation of a dinuclear rare earth metal complex comprising a bridging 2,2'-azobispyridyl radical anion, (CpY)(μ-abpy˙), is presented, which was obtained from a one-electron chemical oxidation of [(CpY)(μ-abpy)]. The unprecedented compounds were characterized by crystallography, spectroscopy and DFT computations. The radical character was proven by EPR spectroscopy.
摘要
本文报道了一种双核稀土金属配合物(CpY)(μ-abpy˙)的首次分离，该配合物包含一个桥连的2,2'-偶氮双吡啶自由基阴离子，它是由[(CpY)(μ-abpy)]经单电子化学氧化得到的。通过晶体学、光谱学和DFT计算对这些前所未有的化合物进行了表征。通过电子顺磁共振光谱证实了其自由基特性。
