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.

Key words: organic-inorganic hybrid material, vanadium oxide, crystal structure, characterization
