Poly[[μ-2,2'-diethyl-1,1'-(propane-1,3-di-yl)di-1H-imidazole-κN:N](μ-5-hy-droxy-isophthalato-κO:O)zinc].
In the title coordination polymer, [Zn(C(8)H(4)O(5))(C(13)H(20)N(4))](n), the Zn(II) ion is coordinated by an O(2)N(2) donor set in a distorted tetra-hedral geometry. The Zn(II) ions are connected by 5-hy-droxy-isophthalate (hbdc) and 2,2'-diethyl-1,1'-(propane-1,3-di-yl)di-1H-imidazole (pbie) ligands, forming a threefold inter-penetrating diamondoid framework. In the pbie ligand, one of the ethyl-imidazole groups is disordered over two positions, with a site-occupancy ratio of 0.670 (9):0.330 (9). An inter-molecular O-H⋯O hydrogen bond is formed between the hy-droxy and carboxyl-ate groups of the hbdc ligands.
