Two unexpected chiral organometallic triangles rather than squares from newly designed 90° chiral di-Pt(II) acceptors were obtained through coordination-driven self-assembly. Their structures were well characterized by multinuclear NMR ((1)H and (31)P) and variable-temperature NMR experiments, ESI-TOF-MS, and elemental analysis. The PM6 semiempirical molecular simulation was employed for the interpretation of the formation and stability of such chiral triangles.
两个意想不到的手性有机金属三角形而不是正方形是通过配位驱动的自组装从新设计的 90°手性二-Pt(II)受体中获得的。它们的结构通过多核 NMR((1)H 和 (31)P)和变温 NMR 实验、ESI-TOF-MS 和元素分析得到了很好的表征。PM6 半经验分子模拟用于解释这种手性三角形的形成和稳定性。
