Poly[[μ-2,2′-diethyl-1,1′-(propane-1,3-di­yl)di-1H-imidazole-κ(2) N (3):N (3′)](μ-5-hy­droxy­isophthalato-κ(2) O (1):O (3))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 tetra­hedral geometry. The Zn(II) ions are connected by 5-hy­droxy­isophthalate (hbdc) and 2,2′-diethyl-1,1′-(propane-1,3-di­yl)di-1H-imidazole (pbie) ligands, forming a threefold inter­penetrating diamondoid framework. In the pbie ligand, one of the ethyl­imidazole groups is disordered over two positions, with a site-occupancy ratio of 0.670 (9):0.330 (9). An inter­molecular O—H⋯O hydrogen bond is formed between the hy­droxy and carboxyl­ate groups of the hbdc ligands.
