Crystal Structure of Sodium Perchloratotriacetatoneptunate(V) Monohydrate Na_3NpO_2(OOCCH_3)_3ClO_4 centre dot H_2O

摘要

The crystal structure of Na_3NpO_2(OOCCH_3)_3ClO_4 centre dot H_2O was studied by single-crystal X-ray diffraction method.The structure is composed of the complex anions NpO_2(OOCCH_3)_3]~(2-),perchlorate anions,Na cations,and water molecules.The oxygen environment of Np(V) is a hexagonal bipyramid whose equatorial plane is formed by the oxygen atoms of three acetate ions.In addition to the acetate anions,the structure contains the perchlorate ion whose oxygen atoms,except for one,are included in the coordination environment of Na~+cations.
