Materials Data on SrUO4 by Materials Project

Abstract

SrUO4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Sr2+ is bonded in a distorted q6 geometry to ten O2- atoms. There are a spread of Sr–O bond distances ranging from 2.57–2.79 Å. U6+ is bonded to six O2- atoms to form edge-sharing UO6 octahedra. There are two shorter (1.91 Å) and four longer (2.20 Å) U–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Sr2+ and one U6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+ and two equivalent U6+ atoms.
