| Abstract: | Reaction of ZnO, malonic acid, 4,4'-bipy (molar ratio is 1∶3∶0.3) in H2O/DMF (V∶V＝4∶1) at 50 ℃ for 3 d gave the title compound {Zn2(mal)2(4,4'-bipy)(H2O)2]?2(H2O)0.25}∞ (mal＝malonate). The compound was characterized by elemental analysis, IR spectrum and single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n with a＝0.71215(16) nm, b＝1.8685(4) nm, c＝0.73890(17) nm, β＝91.486(5)°, V＝0.9829(4) nm3, Z＝4, Dc＝1.811 g/cm3, Mr＝268.03, F(000)＝542, μ＝25.02 cm－1, R1＝0.0499 and wR2＝0.1374. The X-ray analysis revealed that the central Zn atom is octahedrally coordinated by four O atoms from three mal ligands, one O atom from H2O and one N atom from 4,4'-bipy. The resulting ZnNO5 octahedron is bridged by 4,4'-bipy and malonate ligands, forming a novel 3D porous structure with its channels filled with water molecules. In addition, the thermal properties of the polymeric compound were also investigated. |
