Crystal assembly based on 3,5-bis(2′-benzimidazole) pyridine and its complexes

Abstract

Imdazole, pyridine and their derivatives have been considered as excellent ligands in supramolecular self-assembly. In this paper, a ligand molecule 3,5-bis (2′-benzimidazole) pyridine (BBP) was prepared, and two different crystal architectures based on the ligand molecule were self-assembled by diffusion/solvothermal ways. Furthermore, several crystal architectures of several relative complexes were also successfully assembled. These crystal structures were well defined by X-ray diffractions. Structural resolutions indicated that, as building blocks, this bibenzimidazole pyridine molecules exhibited coordination varieties in constructing the crystal architectures based on its related complexes.
