Poly[[μ2-2,2′-diethyl-1,1′-(butane-1,4-diyl)diimidazole-κ2N3:N3′](μ2-5-hydroxyisophthalato-κ2O1:O3)zinc]
Abstract
In the title coordination polymer, [Zn(C8H4O5)(C14H22N4)]n, the ZnII cation is coordinated by an O2N2 donor set in a distorted tetrahedral geometry. The ZnII ions are linked by μ2-OH-bdc (OH-H2bdc = 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.
