Materials Data on UV2O8 by Materials Project
UV2O8 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. U6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of U–O bond distances ranging from 1.87–2.63 Å. V5+ is bonded to five O2- atoms to form distorted corner-sharing VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.66–2.21 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one U6+ and one V5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent V5+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent V5+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to two equivalent U6+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one V5+ atom.
