| Abstract: | A new organic-inorganic hybrid Mn(H2O)(2,2'-bipy)V2O6] has been prepared,and the new solid has been characterized by single X-ray structure analysis,thermogravimetric analysis,and IR spectroscopic studies.The results show the following crystal data:orthormbic space group is Pca2(1),and the cell parameters are a=9.170 2(2),b=10.477 3(8),c=14.523 1(3)?,V=1 393.54(10)?3 and Z=4.Its structure comprises VO4 chains composed of VO4 tetrahedra and MnN2O4 octahedron layers which connect VO4 chains.The 2,2'-bipyridyl groups bonded to the Mn centers in the layer are projecting outward to occupy regions in between the successive metal layer.Such layers are further interlinked by π—π interactions. |
