Unexpected Self-Assembly of Chiral Triangles from 90° Chiral Di‑Pt(II) Acceptors

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 (1H and 31P) 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.
