A designed dimetallic Fe(II) helicate made with biphenylene-bridged bispyrazolylpyridine ligands and exhibiting a process of spin crossover at temperatures above ambient is shown to encapsulate an = 5/2 tris-oxalato Fe(III) ion. The spin relaxation dynamics of this guest are strongly reduced upon encapsulation.
一种由联亚苯基桥联双吡唑基吡啶配体制备的、在高于环境温度时呈现自旋交叉过程的设计型双金属铁（II）螺旋配合物，被证明能包封一个自旋量子数S = 5/2的三草酸根合铁（III）离子。该客体的自旋弛豫动力学在被包封后大幅降低。
