A uranylcontaining compound [U(CO3)3(H2O)2]·2H2O has been synthesized under hydrothermal condition and characterized by X-ray single-crystal analysis. Crystal structural analysis indicates that this compound consists of three CO32- molecules, one U6+. The results reveal that the title compound presents a 3D frame work built up by O- H … O week hydrogen bonds interactions. The central uranium atom is eight-coordinated through three CO32 - molecules and two H2O. The compound shows a coplanar hexagonal network structure, each hexagon containing a hexagonal hole with a water moleculet.
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。
