摘要:合成并表征了新化合物[Mn(H2O)(2,2′-bipy)V2O6],且对化合物进行了相应的红外、热重分析.结果表明:该化合物的空间群是Pca2(1),其晶胞参数为a=9.170 2(2),b=10.477 3(8),c=14.523 1(3)?!,V=1 393.54(10) ?!3且Z=4;该化合物的结构特征是钒氧四面体[VO4]以共顶点构成的钒氧链,[MnN2O4]八面体将钒氧链连成层;配体2,2′-联吡啶则分布于层的上下两侧,并以π—π相互作用将层与层之间连接起来.

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
