【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=9.1702(2),b=10.4773(8),c=14.5231(3),V=1393.54(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.更多还原

【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.更多还原
