The reaction between non-aqueous uranyl silylamide (UO2[N(SiMe3)2]2·2THF) under anaerobic conditions or uranyl acetate (UO2(OAc)2·2H2O) under standard laboratory conditions and dipyriamethryin affords a bench-stable uranyl complex. Competition studies as well as DFT calculations provide support for the observed selectivity for the uranyl cation over trivalent lanthanide and multiple transition metal precursors.
