| Abstract: | A new organic-inorganic hybrid composed of 3D pure inorganic framework and piperazine and water guests-(Hpip)2{Co(H2O)4}4(H2W12O42)]·10H2O(pip=piperazine) was synthesized with conventional method and characterized by element analysis,infrared spectroscopy,thermal analysis and single-crystal X-ray diffraction techniques.In the compound,H2W12O42]10-anion is eight-dentate ligand and coordinates to eight Co2+ ions;Co2+ ion acts as μ2-bridge which links two H2W12O42]10-anions,and thus a 3D pure-inorganic framework is formed.Guests piperazine and lattice water molecules are filled in the chennals through forming a lot of hydrogen bonds with the framework. |
