摘要

The title compound, poly[(μ 2 ‐formato‐κ 3 O , O ′: O )[μ 2 ‐4‐(pyridin‐4‐yl)benzoato‐κ 3 N : O , O ′]zinc(II)], [Zn(C 12 H 8 NO 2 )(HCOO)] n , has been synthesized in situ and characterized by thermogravimetric analysis (TGA) and single‐crystal and powder X‐ray diffraction analyses. The polymer contains two independent structural units in the asymmetric unit. These are constructed from Zn 2+ ions, 4‐(pyridin‐4‐yl)benzoate (4‐pbc) bridges and in‐situ ‐generated formate ligands, forming two similar two‐dimensional (2D) layer structures. These similar 2D layers are arranged alternately and are linked with each other by dense C—H…O hydrogen bonds to generate a three‐dimensional (3D) supramolecular framework. The crystal is pseudomerohedrally twinned about [201]. Compared with free 4‐Hpbc, the polymer exhibits a red shift and significantly enhanced solid‐state luminescence properties.

O氢键彼此连接，以产生三维（3D）超分子框架。晶体是关于[201]的伪币孪生孪生。与游离4-HPBC相比，聚合物表现出红移和显着增强的固态发光性能。
