Iron(II) Complexes of 2,6-Di[4-(ethylcarboxy)pyrazol-1-yl]pyridine with Reversible Guest-Modulated Spin-Crossover Behavior.

ABSTRACT: Three solvatomorphs of the iron(II) complex of 2,6-di[4-(ethylcarboxy)pyrazol-1-yl]pyridine (bpCOOEt₂p) of formulas [Fe(bpCOOEt₂p)₂](ClO₄)₂·1.5MeNO₂ (1), [Fe(bpCOOEt₂p)₂](ClO₄)₂·MeNO₂ (2), and [Fe(bpCOOEt₂p)₂](ClO₄)₂·2MeNO₂ (3) have been prepared and characterized. They show interesting spin-crossover (SCO) properties ranging from partial to complete thermal spin transitions and a light-induced excited spin-state trapping (LIESST) effect. In solvatomorph 2, a robust structure is formed with channels that enable the entrance or removal of solvent molecules by vapor diffusion without losing
