In the title coordination polymer, Zn(C(8)H(4)O(5))(C(13)H(20)N(4)), 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.
在标题配位聚合物[Zn(C₈H₄O₅)(C₁₃H₂₀N₄)]ₙ中,Zn(II)离子由一个O₂N₂供体基团以扭曲的四面体几何构型配位。Zn(II)离子通过5-羟基间苯二甲酸(hbdc)和2,2'-二乙基-1,1'-(丙烷-1,3-二基)二-1H-咪唑(pbie)配体相连,形成一个三重互穿的类金刚石骨架。在pbie配体中,其中一个乙基咪唑基团在两个位置上无序,占位比为0.670 (9):0.330 (9)。hbdc配体的羟基和羧酸盐基团之间形成了分子间O—H⋯O氢键。
