摘要：

Dinuclear [(TPyA) Fe-II(THBQ(2-))Fe-II(TPyA)](BF4)(2) (1) possesses hydrogen bonding interactions that form a 1-D chain, and pi-pi interactions between the 1-D chains that give rise to a 2- Dsupramolecular- 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.
