Materials Data on UPbO4 by Materials Project
PbUO4 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. U6+ is bonded to six O2- atoms to form corner-sharing UO6 octahedra. The corner-sharing octahedra tilt angles range from 43–47°. There are a spread of U–O bond distances ranging from 1.93–2.22 Å. Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.45–3.10 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one U6+ and three equivalent Pb2+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent U6+ and two equivalent Pb2+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent U6+ and one Pb2+ atom.
