Abstract
In the title coordination polymer, {[Zn(C9H7NO4)(C10H14N4)]·2H2O}n, the ZnII ion displays a distorted tetrahedral geometry with two imidazole N atoms from two 1,1′-(butane-1,4-diyl)bis(imidazole) (bbi) ligands and two carboxylate O atoms from two 2,6-dimethylpyridine-3,5-dicarboxylate (dpdc) ligands. The bbi and dpdc ligands bridge the ZnII ions, forming layers parallel to (011). O—H...O and O—H...N hydrogen bonds and π–π interactions between the imidazole rings [centroid–centroid distance = 3.807 (5) Å] connect the layers. Two of the three uncoordinated water molecules are disordered, each over two 0.25-occupancy positions.
