Representative work: Synthesis of a plutonium(III) molybdate bromide, PuMoO4Br(H2O), has been accomplished using hydrothermal techniques in an inert-atmosphere glovebox. The compound is green in color, which is in stark contrast to the typical blue color of plutonium(III) complexes. The unusual color arises from the broad charge transfer (CT) spanning from approximately 300 to 500 nm in the UV-vis-near-IR spectra. Repeating the synthesis with an increase in the reaction temperature results in the formation of a plutonium(IV) molybdate, Pu3Mo6O24(H2O)2, which also has a broad CT band and red-shifted f-f transitions. Performing an analogous reaction with neodymium produced a completely different product, [Nd(H2O)3 Abstract MoO 3 and HBr‐reduced weapons‐grade PuOCl 2 or NdBr 3 are used for the hydrothermal synthesis of Pu III MoO 4 Br(H 2 O) (I), Pu IV 3 Mo 6 O 24 (H 2 O) 2 (II), and [Nd(H 2 O) 3 ] [NdMo 12 O 42 ]·2H 2 O (III) (PTFE‐lined autoclave, 200 °C for (I) and (III), 230 °C for (II), 3 d)
