A truncated triangular prism constructed by using imidazole–terpyridine building blocks

Abstract

The construction of low-symmetry topological supramolecular structures using bistable building blocks remains challenging. We report an unusual truncated triangular prismatic cage with D_3h symmetry using a ligand with both cis- and trans-configurations upon coordination with metal. This work provides new ideas and methods for the future synthesis of low-symmetry topological supramolecules.
