Abstract

Dinuclear [(TPyA)Fe^II(THBQ^2–)Fe^II(TPyA)](BF₄)₂ (1) possesses hydrogen bonding interactions that form a 1-D chain, and π–π interactions between the 1-D chains that give rise to a 2-D supramolecular-layered structure, inducing hysteresis in the spin crossover behavior; 1 has shown spin crossover behavior around 250 K with thermal hysteresis and ferromagnetic interactions at low temperature.
