ABSTRACT: In the title coordination polymer, {[Zn(C(9)H(7)NO(4))(C(10)H(14)N(4))]·2H(2)O}(n), the Zn(II) ion displays a distorted tetra-hedral geometry with two imidazole N atoms from two 1,1'-(butane-1,4-di-yl)bis-(imidazole) (bbi) ligands and two carboxyl-ate O atoms from two 2,6-dimethyl-pyridine-3,5-dicarboxyl-ate (dpdc) ligands. The bbi and dpdc ligands bridge the Zn(II) ions, forming layers parallel to (011). O-H?O and O-H?N hydrogen bonds and ?-? inter-actions between the imidazole rings [centroid-centroid distance = 3.807?(5)?Å] connect the layers. Two of the three uncoordinated water mol-ecules are disordered, each over two 0.25-occupancy positions.
