Abstract
The solvothermal synthesis of uranyl nitrate with 4,4′-oxybis(benzoic acid) produces a coordination polymer [(UO2)(C15H8O5)(DMF)]n with coordinated DMF residing in the void space. This compound consists of one-dimensional chains that extend down [0 1 0] from UO7 pentagonal bipyramidal monomers. Thermogravimetric analysis indicates that the material loses the coordinated DMF ligand at 200 °C. No sensitized uranyl emission is seen within this system and the only other uranyl compound reported with the same target linker, but weak emission from the organic linker is observed and justified through molecular modeling studies. This system is able to convert between the DMF coordinated and previously reported water coordinated systems upon treatment with water or DMF, respectfully. The title compound showed marked resistance to transformation and/or degradation in a host of other organic solvents.
