Spin Transition and Structural Transformation in a Mononuclear Cobalt(II) Complex.

A mononuclear compound, [Co(II)(pyterpy)2](PF6)2·2CH3OH [2; pyterpy = 4'-(4‴-pyridyl)-2,2':6',2″-terpyridine], shows a phase-transition-coupled, abrupt spin transition with a 9 K wide hysteresis that can transform to a spin-crossover compound, [Co(II)(pyterpy)2](PF6)2·2CH2Cl2·CH3OH (3).
