| Abstract: 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. CCDC: 658853. |
