Synthesis, structure, and property of a cd(II) 3D coordinated polymer with 2-fold parallel interpenetrated network based on 5-(4-hydroxypyridinium-1-yl) isophthalic acid ligand

<p>A Cd(II) coordination polymer, {[Cd(L)(1,4-bbi)<sub>0.5</sub>(H<sub>2</sub>O)]·H<sub>2</sub>O}<i><sub>n</sub></i> (<b>1</b>), where H<sub>2</sub>L = 5-(4-hydroxypyridinium-1-ylmethyl)isophthalic acid, 1,4-bbi = 1,1′-(1,4-butanediyl)bis(imidazole), has been hydrothermally synthesized and structurally characterized by X-ray diffraction analyses and further characterized by infrared spectra (IR), elemental analyses, PXRD, and thermogravimetric (TG) analyses. Compound <b>1</b> reveals a 2-fold interpenetrating 3D framework with (4·8<sup>2</sup>·10<sup>3</sup>) (4·8<sup>2</sup>) topology, and the Cd center has a distorted octahedral environment. Meanwhile, the luminescent property of the title compound (<b>1</b>) has also been investigated in detail.</p>
