Identification of the Formal +2 Oxidation State of Neptunium: Synthesis and Structural Characterization of {Np II [C 5 H 3 (SiMe 3 ) 2 ] 3 } 1–
Here in this paper, we report a new formal oxidation state for neptunium in a crystallographically characterizable molecular complex, namely Np 2+ in [K(crypt)][Np II Cp" 3 ] [crypt = 2.2.2-cryptand, Cp" = C 5 H 3 (SiMe 3 ) 2 ]. Density functional theory calculations indicate that the ground state electronic configuration of the Np 2+ ion in the complex is 5f 4 6d 1 .
