A large hysteresis centered around room temperature represents one of the mandatory goals of research on functional switchable materials. In the thoroughly studied field of spin-crossover, such behaviour appears very rarely and essentially concerns coordination networks. A new compound showing a large spin-crossover hysteresis spanning room temperature demonstrates in a definitive manner that this goal is achievable in molecular discrete compounds without damaging the single-crystal character.
以室温为中心的大滞后现象是功能可切换材料研究的一个必要目标。在经过充分研究的自旋交叉领域，这种行为非常罕见，且主要涉及配位网络。一种新的化合物在室温范围内呈现出大的自旋交叉滞后现象，这明确表明在不破坏单晶特性的分子离散化合物中可以实现这一目标。
