Poly[[μ(2)-2,2′-diethyl-1,1′-(butane-1,4-di­yl)diimidazole-κ(2) N (3):N (3′)](μ(2)-5-hydroxy­isophthalato-κ(2) O (1):O (3))zinc]

In the title coordination polymer, [Zn(C(8)H(4)O(5))(C(14)H(22)N(4))](n), the Zn(II) cation is coordinated by an O(2)N(2) donor set in a distorted tetra­hedral geometry. The Zn(II) ions are linked by μ(2)-OH-bdc (OH-H(2)bdc = 5-hy­droxy­isophthalic acid) and bbie ligands [bbie = 2,2′-diethyl-1,1′-(butane-1,4-di­yl)diimidazole], forming a two-dimensional layer parallel to the ab plane. The layers are further connected through intermolecular C—H⋯O and O—H⋯O hydrogen bonds, forming a three-dimensional supramolecular structure. In the bbie ligand, the two C atoms in the ethyl group are each disordered over two positions with a site-occupancy ratio of 0.69:0.31.
