Using the ligand pyridazine-3,6-dicarboxylate (H2pzdc), a coordination polymer [Cd2(pzdc)2(H2O)4] was synthesized and characterized by elemental analysis, thermal analysis, IR and single-crystal X-ray diffraction. The complex crystallizes in the tetragonal system with space group I41/a. The crystallographic data are: a=1.470 6(4) nm, c=1.489 8(6) nm, V=3.222 0(19) nm3, Z=16, μ=2.725 mm-1, Dc=2.594 g·cm-3, R1=0.017 8, wR2=0.044 6. In the complex, the cadmium(Ⅱ) ions with the eight-coordinated dodecahedral geometry are linked by the pzdc ligands to generate one-dimensional chains, which are associated into the three-dimensional architecture via O-H…O hydrogen bonding.
