Abstract
A new Pu(VII) compound, Na3[PuO4(OH)2]·2H2O, was prepared by X-ray diffraction analysis, and its structure was studied. To reveal the character of actinide contraction in going from Np(VII) to Pu(VII), the geometric parameters of the tetragonal-bipyramidal surrounding of Pu(VII) in the [PuO4(OH)2]3− anion were compared with those of Np(VII) in the previously studied isostructural compound Na3[NpO4(OH)2]·2H2O. To reveal the specific feature of hydrogen bonding in crystals of the general composition Na3[NpO4(OH)2]·nH2O (n = 0, 2, 4), the structure of the compound Na3[NpO4(OH)2]·4H2O studied previously by the photographic method was refined. The effect of hydrogen bonds on the geometric characteristics of the coordination polyhedra of the Np and Na atoms was considered.
