Poly[[μ-2,2′-diethyl-1,1′-(propane-1,3-diyl)di-1H-imidazole-κ2N3:N3′](μ-5-hydroxyisophthalato-κ2O1:O3)zinc]

Abstract

In the title coordination polymer, [Zn(C8H4O5)(C13H20N4)]n, the ZnII ion is coordinated by an O2N2 donor set in a distorted tetrahedral geometry. The ZnII 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.
