In the first Na1+ site, Na1+ is bonded to six equivalent O2- atoms to form NaO6 octahedra that share corners with six equivalent UO6 octahedra, edges with three UO6 octahedra, and edges with nine NaO6 octahedra. The corner-sharing octahedral tilt angles are 11°. All Na–O bond lengths are 2.60 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with six NaO6 octahedra, edges with six NaO6 octahedra, and edges with six UO6 octahedra. The corner-sharing octahedra tilt angles range from 0–16°. There are two shorter (2.42 Å) and four longer (2.45 Å) Na–O bond lengths. In the third Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with two equivalent UO6 octahedra, corners with four NaO6 octahedra, edges with four UO6 octahedra, and edges with eight NaO6 octahedra.
