The Materials Project

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 45°. There are a spread of U–O bond distances ranging from 1.83–2.34 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent U6+ and one H1+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one U6+ atom.
