The A mixed crystal compound Co(0.8)Fe(0.2)(C16-terpy)(2)(2) (2) (C16-terpy is 4'-hexadecyloxy-2,2':6',2''-terpyridine) with long alkyl chains was prepared by mixing Co(C16-terpy)(2)(2) (1), which exhibits unique magnetic behavior, and the diamagnetic iron(II) compound Fe(C16-terpy)(2)(2) (3). The long-lived metastable state in the frozen-in effect was observed for the first time in the spin-crossover cobalt(II) compound 2. Furthermore, relaxation from metastable to stable states was very slow because of a large structural transition resulting from the long alkyl chains.

混合晶体化合物Co(0.8)Fe(0.2)(C16-terpy)(2)(2)(2)(其中 C16-terpy 是 4'-己氧基-2,2':6',2''-三联吡啶)通过混合具有独特磁行为的Co(C16-terpy)(2)(2)(1)和反磁性的铁(II)化合物Fe(C16-terpy)(2)(2)(3)制备。首次在自旋交叉钴(II)化合物 2 中观察到冻结效应中的长寿命亚稳态。此外,由于长烷基链导致的大结构转变,从亚稳态到稳定状态的弛豫非常缓慢。
