Triptycene-based diiron(II) and dizinc(II) mesocates were obtained using a novel rigid ligand with two pyridylbenzimidazole chelating units fused into the triptycene scaffold. Studies on the diiron(II) assembly in solution showed that the complex undergoes thermal-induced one-step spin-crossover with T_1/2 at 243 K (Evans method).

基于三蝶烯的二铁(II) 中间酸盐：溶液中的自旋交叉

使用一种新型刚性配体，将两个吡啶基苯并咪唑螯合单元融合到三蝶烯支架中，获得了基于三蝶烯的二铁( II )和二锌( II )中间酸。对溶液中二铁 ( II ) 组装的研究表明，该配合物在 243 K 下经历热诱导的一步自旋交叉T _1/2（埃文斯法）。
