Spin-crossover iron(<scp>ii</scp>) complex showing thermal hysteresis around room temperature with symmetry breaking and an unusually high<i>T</i>(LIESST) of 120 K

Abstract

We report a Fe(ii) complex based on 4',4'' carboxylic acid disubstituted dipyrazolylpyridine that shows a spin-crossover close to room temperature associated to a crystallographic phase transition and the LIESST effect with a high T(LIESST) of 120 K.
