Abstract

We report a triazole-based trinuclear complex as the first example that displays a complete one-step first-order [HS-HS-HS] ↔ [LS-LS-LS] spin transition at 318 K. The strong ferro-elastic interactions, between the three metal centers, have been identified as the source of the concerted spin transition in this trinuclear complex.

摘要

我们报道了一种基于三唑的三核配合物，这是首例在318 K时呈现出完整的一步一级[高自旋-高自旋-高自旋]↔[低自旋-低自旋-低自旋]自旋转变的例子。三个金属中心之间强烈的铁弹性相互作用已被确定为该三核配合物协同自旋转变的根源。
