Synthesis of Bimetallic Uranium and Neptunium Complexes of a Binucleating Macrocycle and Determination of the Solid-State Structure by Magnetic Analysis
Syntheses of the bimetallic uranium(III) and neptunium(III) complexes [(Ul)(2)(L)], [(Npl)(2)(L)], and [{U(BH4)}(2)(L)] of the Schiff-base pyrrole macrocycles L are described. In the absence of single-crystal, structural data, fitting of the variable-temperature solid-state magnetic data allows the prediction of polymeric structures for these compounds in the solid state.
