Title: Materials Data on UVAgO6 by Materials Project

Abstract

UVAgO6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent UO7 pentagonal bipyramids, corners with two equivalent VO5 trigonal bipyramids, an edgeedge with one UO7 pentagonal bipyramid, and edges with two equivalent VO5 trigonal bipyramids. There are a spread of U–O bond distances ranging from 1.83–2.43 Å. V5+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent UO7 pentagonal bipyramids, edges with two equivalent UO7 pentagonal bipyramids, and an edgeedge with one VO5 trigonal bipyramid. There are a spread of V–O bond distances ranging from 1.65–1.97 Å. Ag1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.28–3.00 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one U6+ and one Ag1+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one U6+, two equivalent V5+, and one Ag1+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometrymore » to one V5+ and one Ag1+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one U6+ and two equivalent Ag1+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent U6+, one V5+, and one Ag1+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent U6+ and one V5+ atom.« less
