研究了自旋交叉铁(II)配合物[Fe(L)(CN)(2)]·H2O(1)。配合物1具有七配位的五方双锥结构，含有一个N3O2大环和两个CN-配体。水分子通过氢键将络合物结合在一起。研究发现，化合物1具有光致激发自旋态俘获(LIESST)效应。弛豫温度在130K以上，这是迄今为止报道的LIESST化合物的最高温度。
The spin-crossover iron(II) complex [Fe(L)(CN)(2)].H2O (1) has been investigated. Complex 1 has a pentagonal bipyramidal structure which is seven-coordinated, containing an N3O2 macrocycle and two CN- ligands. Water molecules bind the complex by means of hydrogen bonding. It was found that the complex 1 exhibited a light-induced excited spin state trapping (LIESST) effect. The relaxation temperature is above 130 K, which is the highest temperature for LIESST compounds reported so far.
