Resumen: 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 S = 5/2 tris-oxalato Fe(iii) ion. The spin relaxation dynamics of this guest are strongly reduced upon encapsulation.
