Title: Materials Data on U(HO2)2 by Materials Project

Abstract

UO2(OH)2 crystallizes in the orthorhombic Pbca space group. The structure is two-dimensional and consists of two UO2(OH)2 sheets oriented in the (0, 0, 1) direction. U6+ is bonded to six O2- atoms to form corner-sharing UO6 octahedra. The corner-sharing octahedral tilt angles are 36°. There are a spread of U–O bond distances ranging from 1.98–2.28 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent U6+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one U6+ and one H1+ atom.
