Abstract
The spin-crossover iron(II) complex [Fe(L)(CN)(2)].H2O (1) has been investi gated. Complex 1 has a pentagonal bipyramidal structure which is seven-coor dinated, containing an N3O2 macrocycle and two CN- ligands. Water molecules bind the complex by means of hydrogen bonding. It was found that the compl ex 1 exhibited a light-induced excited spin state trapping (LIESST) effect. The relaxation temperature is above 130 K, which is the highest temperatur e for LIESST compounds reported so far.
