Temperature-dependent metalation of the new hexadentate ligand (tris(5-(pyridin-2-yl)-1H-pyrrol-2-yl)methane; HTPM) enables the selective synthesis of both mononuclear (i.e. Na(THF)[Fe(TPM)], kinetic product) and trinuclear (i.e. Fe(TPM), thermodynamic product) complexes. Exposure of Na(THF)[Fe(TPM)] to FeCl or ZnCl triggers cluster expansion to generate homo- or heterometallic trinuclear complexes, respectively. The developed approach enables systematic variation of ion content in isostructural metal clusters via programmed assembly.
新型六齿配体（三（5-（吡啶-2-基）-1H-吡咯-2-基）甲烷；HTPM）的温度依赖性金属化反应能够选择性地合成单核（即Na(THF)[Fe(TPM)]，动力学产物）和三核（即Fe(TPM)，热力学产物）配合物。将Na(THF)[Fe(TPM)]暴露于FeCl或ZnCl会引发簇扩展，分别生成同金属或异金属三核配合物。所开发的方法能够通过程序组装实现同构金属簇中离子含量的系统变化。
