A novel hydrogen-bonded metal-organic framework (H-MOF) Co(HL)(HO) (1·solv), in which L = 2,2':6',2''-terpyridine-5,5"-diyl biscarboxylate, was prepared. An intermolecular single H-bond between carboxy and carboxylate sites was present in this compound. The crystal structure of 1·solv showed a 4-fold interpenetrating H-bonded diamond framework. After the desorption of the crystal solvents, 1·desolv exhibited normal and reverse spin-crossover (SCO) behaviours, providing an asymmetric thermal hysteresis loop.
制备了一种新型氢键金属有机框架（H-MOF）Co(HL)(HO) (1·solv)，其中L = 2,2':6',2''-三联吡啶-5,5''-二羧酸二酯。该化合物中羧基和羧酸盐位点之间存在分子间单氢键。1·solv的晶体结构显示出四重互穿的氢键金刚石框架。晶体溶剂解吸后，1·desolv表现出正常和反向自旋交叉（SCO）行为，提供了一个不对称的热滞回线。
