Materials Data on UP2(PbO5)2 by Materials Project
UP2(PbO5)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. U6+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of U–O bond distances ranging from 1.82–2.60 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Pb–O bond distances ranging from 2.34–3.20 Å. In the second Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.39–3.21 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.55 Å) and two longer (1.56 Å) P–O bond length. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.54 Å) and two longer (1.57 Å) P–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one P5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one U6+ and one Pb2+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent U6+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one U6+ and two Pb2+ atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one U6+, two Pb2+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to one U6+, one Pb2+, and one P5+ atom.
