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…CI, C-H…CI 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.
