The solvent dependence of spin-crossover behavior and metastability of the FeII complex [FeL222N3O2(CN)2]·H2O were investigated. Compared with the pristine and the dehydrated complex, the rehydrated complex shows enhanced metastability and an increased spin-transition temperature. This solvent dependence indicates new possibilities to improve metastability toward further applications.
