Materials Data on LuP by Materials Project

PLu is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Lu3+ is bonded to six equivalent P3- atoms to form a mixture of corner and edge-sharing LuP6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Lu–P bond lengths are 2.77 Å. P3- is bonded to six equivalent Lu3+ atoms to form a mixture of corner and edge-sharing PLu6 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on LuP5 by Materials Project

LuP5 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Lu3+ is bonded in a 8-coordinate geometry to eight P+0.60- atoms. There are a spread of Lu–P bond distances ranging from 2.87–2.99 Å. There are three inequivalent P+0.60- sites. In the first P+0.60- site, P+0.60- is bonded to two equivalent Lu3+ and two P+0.60- atoms to form a mixture of corner and edge-sharing PLu2P2 tetrahedra. There are one shorter (2.17 Å) and one longer (2.22 Å) P–P bond lengths. In the second P+0.60- site, P+0.60- is bonded to two equivalent Lu3+ and two equivalent P+0.60- atoms to form distorted corner-sharing PLu2P2 tetrahedra. Both P–P bond lengths are 2.21 Å. In the third P+0.60- site, P+0.60- is bonded to one Lu3+ and three P+0.60- atoms to form distorted PLuP3 tetrahedra that share corners with nine PLu2P2 tetrahedra and an edgeedge with one PLuP3 tetrahedra. The P–P bond length is 2.19 Å.
