  "abstract": "<p>The synthesis of a tetravalent neptunium amidinate [NpCl((S)\u2010PEBA)3] (1) ((S)\u2010PEBA=(S,S)\u2010N,N&prime;\u2010bis\u2010(1\u2010phenylethyl)\u2010benzamidinate) is reported. This complex represents the first structurally characterized enantiopure transuranic compound. Reactivity studies with halide/pseudohalides yielding [NpX((S)\u2010PEBA)3] (X=F (2), Br (3), N3 (4)) have shown that the chirality\u2010at\u2010metal is preserved for all compounds in the solid state. Furthermore, they represent an unprecedented example of a structurally characterized metal&ndash;organic Np complex featuring a Np&minus;Br (3) bond. In addition, 4 is the only reported tetravalent transuranic azide. All compounds were additionally characterized in solution using para\u2010magnetic NMR spectroscopy showing an expected C3\u2010symmetry at low temperatures.</p>",
