Materials Data on BaU2P2O19 by Materials Project
Abstract
BaU2P2O19 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Ba is bonded in a 9-coordinate geometry to eight O atoms. There are a spread of Ba–O bond distances ranging from 2.71–3.18 Å. There are two inequivalent U sites. In the first U site, U is bonded to six O atoms to form UO6 octahedra that share corners with four PO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.85–2.29 Å. In the second U site, U is bonded to six O atoms to form UO6 octahedra that share corners with four PO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.81–2.35 Å. There are two inequivalent P sites. In the first P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with four UO6 octahedra. The corner-sharing octahedra tilt angles range from 32–40°. There is two shorter (1.55 Å) and two longer (1.56 Å) P–O bond length. In the second P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with four UO6 octahedra. The corner-sharing octahedra tilt angles range from 24–53°. There are a spread of P–O bondmore »
