Materials Data on Sr2UO4 by Materials Project
Sr2UO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.35–3.14 Å. U4+ is bonded to six O2- atoms to form corner-sharing UO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.19 Å) and four longer (2.21 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 Sr2+ and one U4+ atom. In the second O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent U4+ atoms to form a mixture of distorted corner, edge, and face-sharing OSr4U2 octahedra. The corner-sharing octahedral tilt angles are 0°.
