摘要:

水热条件下合成了一种含铀的超分子化合物[UO2Cl4][phenH]2(phen=1,10-邻菲罗啉),进行了X射线单晶衍射、红外光谱、紫外光谱和荧光光谱分析。 晶体结构分析表明,该化合物由2个[phenH]+阳离子和1个阴离子[UO2Cl4]2-组成。 红外光谱和X射线单晶衍射表明,标题化合物的三维框架是由N-H…Cl、C-H…Cl和C-H…O弱氢键相互作用所构建。 中心U原子是六配位,有4个Cl原子和2个O原子。 此外,没参与配位的phen利用氢键和π…π堆积与[UO2Cl4]2-相互作用。 含U原子的阴离子是一种扭曲八面体结构。 利用溶胶-凝胶法合成了化合物的PVA薄膜。 标题化合物和薄膜均有较强的荧光性。CCDC:713149

Abstract:

A uranyl-containing supramolecular compound [UO2Cl4][phenH]2(phen=1,10-phenanthroline) has been synthesized under hydrothermal condition and characterized by X-ray singlecrystal analysis, IR, UV and fluorescence spectrum. Crystal structural analysis indicates that it consists of two [phenH]+ and one heteropolyanion of [UO2Cl4]2- in the asymmetric unit. The results of IR spectra and X-ray single crystal diffraction reveal that the title complex present a 3D framework built up by N-H…Cl, C-H…Cl and C-H…O weak hydrogen bonds interactions. The central uranium atom has a distorted octahedral environment and is coordinated by four Cl atoms and two O atoms. In addition, there are also uncoordinated protonated 1,10-phenanthroline bonded by hydrogen bonds and π…π stacking interactions, which is rarely observed in previous reports. Its polyvinyl alcohol(PVA) film was casted by a sol-gel process and characterized by IR, UV and fluorescence spectrum. Both the title compound and its film show strong fluorescence. CCDC:713149
