The material structure described by Na2UO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. Na(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. U(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing UO6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(2) is bonded in a linear geometry to one Na(1) and one U(1) atom. In the second O site, O(1) is bonded to four equivalent Na(1) and two equivalent U(1) atoms to form a mixture of face, corner, and edge-sharing ONa4U2 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
