摘要

本研究首次分离出一种包含桥接 2,2'-偶氮二吡啶基阴离子 [(Cptet2Y)2(μ-abpy˙)](BPh4)的双核稀土金属配合物，该配合物是通过对 [(Cptet2Y)2(μ-abpy)]进行单电子化学氧化得到的。通过晶体学、光谱学和 DFT 计算对这种前所未有的化合物进行了表征。EPR 光谱证明了其自由基特性。

Implementation of 2,2'-azobispyridine radical mono- and dianions in dinuclear rare earth metal complexes.

The seminal isolation of a dinuclear rare earth metal complex comprising a bridging 2,2'-azobispyridyl radical anion, [(Cp^tet₂Y)₂(μ-abpy˙)](BPh₄), is presented, which was obtained from a one-electron chemical oxidation of [(Cp^tet₂Y)₂(μ-abpy)]. The unprecedented compounds were characterized by crystallography, spectroscopy and DFT computations. The radical character was proven by EPR spectroscopy.
