Radiochemistry Aims and scope

Abstract

A new Pu(VII) compound, K3PuO4(OH)2·2H2O, was synthesized, and its structure was studied by single crystal X-ray diffraction. This compound is isostructural to the previously described K3NpO4(OH)2·2H2O. The structure of the latter compound was redetermined to obtain more precise interatomic distances in the NpO2(OH) 3−2 anion. Changes in An-O bond lengths in the tetragon-bipyramidal coordination polyhedron of the compounds K3AnO4(OH)2·2H2O in going from Np(VII) to Pu(VII) were considered.
