Abstract

Mononuclear spin-crossover complex Fe^II(L)₂·CH₃OH (1·CH₃OH) and its desolvated product 1 exhibit abrupt spin transitions around room temperature. 1 also shows a light induced excited spin state trapping (LIESST) effect and a light induced thermal hysteresis (LITH) phenomenon at low temperature.
