Title: A new Zn<sup>II</sup> coordination polymer based on 4-(pyridin-4-yl)benzoic and formic acids: <i>in-situ</i> synthesis, crystal structure and luminescence properties
Abstract: 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.
