The syntheses of novel chiral M(II) bis(terpyridine) cage complexes Fe(L1)2-c and Ru(L1)2-c are described. The extraordinary design of the precursors Fe(L1)2 and Ru(L1)2 allows perfect preorganization for the final closing step. Due to the rigidity of the spacers between the two terpyridine moieties, the two isolated enantiomers barely racemize at room temperature in solution. The stable and axially chiral bis(terpyridine) Fe(II) and Ru(II) complexes were fully characterized by NMR-spectroscopy, UV-Vis spectroscopy, electrochemical measurements, high resolution mass spectrometry, circular dichroism measurements, and X-ray structural analysis.

手性大环三联吡啶配合物†
描述了新型手性M（II）双（叔吡啶）笼络合物Fe（L1）2 -c和Ru（L1）2 -c的合成。前驱体Fe（L1）2和Ru（L1）2的非凡设计为最终的封闭步骤提供了完美的预组织。由于两个三联吡啶部分之间的间隔基的刚性，两个分离的对映异构体在室温下几乎不消旋成溶液。稳定且轴向手性的双（三联吡啶）Fe（II）和Ru（II）配合物已通过NMR光谱，UV-Vis光谱，电化学测量，高分辨率质谱，圆二色性测量和X射线结构分析进行了充分表征。
