Materials Data on U3O10 by Materials Project

Abstract

U3O10 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent U sites. In the first U site, U is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of U–O bond distances ranging from 1.88–2.66 Å. In the second U site, U is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of U–O bond distances ranging from 1.84–2.59 Å. In the third U site, U is bonded in a distorted octahedral geometry to six O atoms. There are a spread of U–O bond distances ranging from 1.92–2.25 Å. There are ten inequivalent O sites. In the first O site, O is bonded in a water-like geometry to two U atoms. In the second O site, O is bonded in a distorted bent 150 degrees geometry to two U atoms. In the third O site, O is bonded in a distorted single-bond geometry to two U atoms. In the fourth O site, O is bonded in a distorted trigonal planar geometry to three U atoms. In the fifth O site, O is bonded in a single-bond geometry to one U atom. In the sixth O site, O is bonded in a 2-coordinate geometry to three U atoms. In the seventh O site, O is bonded in a distorted single-bond geometry to two equivalent U atoms. In the eighth O site, O is bonded in a bent 120 degrees geometry to two U atoms. In the ninth O site, O is bonded in a single-bond geometry to one U atom. In the tenth O site, O is bonded in a bent 120 degrees geometry to two U atoms.
