Materials Data on UCu2(PO5)2 by Materials Project
UCu2(PO5)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. U6+ is bonded to six O2- atoms to form UO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are two shorter (1.83 Å) and four longer (2.28 Å) U–O bond lengths. Cu2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.98–2.66 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent UO6 octahedra. The corner-sharing octahedral tilt angles are 26°. There is two shorter (1.52 Å) and two longer (1.58 Å) P–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one U6+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one U6+ and two equivalent Cu2+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cu2+ and one P5+ atom.
