Abstract
A Hofmann-type two-step spin-crossover (SCO) complex with a pyrimidine derivative ligand, Fe(4-methylpyrimidine)2[Au(CN)2]2, was synthesized, and this complex shows a two-step SCO phenomenon in the intermediate state. Symmetry breaking also occurs in the intermediate state. These results reveal three spin states within the complex for high-spin (HS), HS0.5LS0.5, and low-spin (LS).
摘要
合成了一种具有嘧啶衍生物配体的霍夫曼型两步自旋交叉（SCO）配合物Fe(4-甲基嘧啶)2[Au(CN)2]2，该配合物在中间态呈现两步SCO现象。中间态还发生了对称性破缺。这些结果揭示了配合物内的三种自旋态，即高自旋（HS）、HS0.5LS0.5和低自旋（LS）。
