Heterometallic zinc uranium oxyfluorides incorporating imidazole ligands

Two heterometallic uranium oxyfluorides with hybrid networks were hydrothermally synthesized by incorporating two imidazoles, 1-（biphenyl-4-yl）-lH-imidazole （bpi） and 1,4-di（1H-imidazol-l-yl）ben- zene （dib）, formulated as Zn（bpi）2（UO2）2（H2O）F6 （1） and Zn（dib）（UO2）F4-0.5H20 （2）. Compound 1 consists o...

Description
Summary:Two heterometallic uranium oxyfluorides with hybrid networks were hydrothermally synthesized by incorporating two imidazoles, 1-（biphenyl-4-yl）-lH-imidazole （bpi） and 1,4-di（1H-imidazol-l-yl）ben- zene （dib）, formulated as Zn（bpi）2（UO2）2（H2O）F6 （1） and Zn（dib）（UO2）F4-0.5H20 （2）. Compound 1 consists of chains of edge-sharing UO2F5 and UO2F4（H20） pentagonal bipyramids, which are linked by Zn（bpi）2 moieties to form the sheet structure with decorated bpi. While in compound 2, sheets of edge- sharing dimers of UO2F5 pentagonal bipyramids and ZnF3N2 polyhedra are linked by dib, creating a pillared three-dimensional framework. The two compounds represent the few examples of heterometallic uranium oxyfluorides incorporating organic ligands. The syntheses, structure as well as the IR spectra, UV-vis spectra and luminescent properties of the bimetallic uranium oxyfluorides are studied.
