reported. The X-ray structure of the reaction product shows that the ligand adopts a pseudo cage-like structure that encapsulates both a proton and an Fe(ii) ion in its cavity. The complex shows an extended helical arrangement that is effectively ‘capped’ at its open end by a hydrogen bonded PF6– counter ion that is symmetrically aligned with the 3-fold axis of the helix. A 1HNMRstudy demonstrated that
报道了新的三脚架三联吡啶联配体的第一类成员,其中Fe(ii)模板合成了氮桥头。反应产物的X射线结构表明,该配体采用伪笼状结构,该结构将质子和Fe(ii)离子包封在其腔内。络合物显示出扩展的螺旋排列,在其开口端被氢键合的PF 6 –抗衡离子有效地“封端”,该抗衡离子与螺旋的3倍轴对称排列。阿1项1 H NMR研究证实了包封的质子可以在CD的酸/碱的条件下可逆地交换3 CN。
