| Abstract: | A polar Cu(II) uranyl diphosphonate, Cu(H2O)4(UO2)3(H2O)2CH2(PO3)2]2·5H2O, has been prepared under mild hydrothermal conditions. This compound has direct linkages between the oxo atoms of the uranyl moieties and the Cu(II) centers. Despite the presence of Cu(II) in the structure, vibronically-coupled emission is still observed, most likely because there are two crystallographically unique uranyl moieties, only one of which bonds to Cu(II). |
