Syntheses,Structure and Properties of Coordination Polymer Constructed Through Azobenzenetetracarboxylic Acid

合成了3,3,′4,4′-偶氮苯四甲酸(H4L)及锰的配合物[Mn2L(H2O)10].4H2O,并用元素分析、荧光光谱、XRD粉末衍射和单晶衍射仪对它们进行了表征。研究结果表明化合物H4L.2H2O通过O-H…O氢键的作用构成2D的网络结构;配合物[Mn2L(H2O)10].4H2O中心锰离子为六配位,其中溶剂分子水和配体L均参与配位,分子间通过O-H…O氢键构成了1D的Z字链结构,而1D链之间通过O-H…O和O-H…N形成2D的网络结构。配合物具有很好的荧光特性。

A compound 3,3＇,4,4＇-Diazenediyldiphthalic acid（H4L） and the manganese（II） complex [Mn2L（H2O）10]·4H2O were synthesized in water solution and characterized by elemental analysis,XRD,single crystal X-ray diffraction and fluorescence spectrum.The structure of H4L·2H2O exhibits interesting two-dimensional networks through the O-H…O bonds.The complex [Mn2L（H2O）10]·4H2O was six-coordinated forms which included the solvent water molecules and one-dimensional Z chain and two-dimensional networks were formed by hydrogen bonds.It has been proved that the complex has fluorescence behavior.
