Isostructural salts of the same complex showing contrasting thermal spin-crossover mediated by multiple phase changes

摘要

Two salts of [FeL2]2+ (L = 2,6-bis[5-methyl-1H- pyrazol-3-yl]pyridine) are isostructural under ambient conditions but show different thermal spin-crossover behaviour, involving a variety of crystallographic phase changes. © 2013 The Royal Society of Chemistry.
