A novel dry synthesis for the uranium(VI) dioxo-diacetohydroxamate (UAHA) complex has been developed. The complex was generated in >80% yield by mechanically grinding solid uranyl acetate dihydrate (UAc) with solid acetohydroxamic acid in stoichiometric amounts. The resulting UO2(AHA)2·4H2O solid is purified by washing with acetone. The stoichiometry was confirmed viacolorimetric assays for U(VI) and AHA. The analogous ferric trisacetohydroxamate complex (FeAHA) was synthesized for comparison. A novel dry synthesis for the uranium(VI) dioxo-diacetohydroxamate (UAHA) complex has been developed.
