Title: Materials Data on Na2UO4 by Materials Project

Abstract

Na2UO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Na1+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of Na–O bond distances ranging from 2.26–3.08 Å. U6+ is bonded to six O2- atoms to form corner-sharing UO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (1.93 Å) and four longer (2.18 Å) U–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to five equivalent Na1+ and one U6+ atom. In the second O2- site, O2- is bonded to four equivalent Na1+ and two equivalent U6+ atoms to form a mixture of distorted corner, edge, and face-sharing ONa4U2 octahedra. The corner-sharing octahedral tilt angles are 0°.
