Title: Materials Data on Ce6Ni20P13 by Materials Project

Abstract

Ce6Ni20P13 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are two inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded to six P3- atoms to form distorted CeP6 pentagonal pyramids that share corners with four equivalent CeP6 pentagonal pyramids, corners with two equivalent NiP5 square pyramids, corners with twelve NiP4 tetrahedra, edges with two equivalent CeP6 pentagonal pyramids, edges with eight NiP4 tetrahedra, and faces with two equivalent CeP6 pentagonal pyramids. There are a spread of Ce–P bond distances ranging from 2.93–2.99 Å.

There are a spread of Ni–P bond distances ranging from 2.31–2.35 Å. In the seventh Ni+1.05+ site, Ni+1.05+ is bonded to four P3- atoms to form NiP4 tetrahedra that share corners with six CeP6 pentagonal pyramids, a cornercorner with one NiP5 square pyramid, corners with six NiP4 tetrahedra, edges with four CeP6 pentagonal pyramids, and edges with four NiP4 tetrahedra. There are a spread of Ni–P bond distances ranging from 2.28–2.33 Å. In the eighth Ni+1.05+ site, Ni+1.05+ is bonded to four P3- atoms to form NiP4 tetrahedra that share corners with four CeP6 pentagonal pyramids, corners with eleven NiP4 tetrahedra, edges with three CeP6 pentagonal pyramids, edges with two equivalent NiP5 square pyramids, and edges with three NiP4 tetrahedra. There are two shorter (2.29 Å) and two longer (2.36 Å) Ni–P bond lengths. There are five inequivalent P3- sites. In the first P3- site, P3- is bonded in a 9-coordinate geometry to four equivalent Ce3+ and five Ni+1.05+ atoms. In the second P3- site, P3- is bonded in a 9-coordinate geometry to two equivalent Ce3+ and seven Ni+1.05+ atoms. In the third P3- site, P3- is bonded in a 3-coordinate geometry to nine Ni+1.05+ atoms. In the fourth P3- site, P3- is bonded in a 9-coordinate geometry to four equivalent Ce3+ and five Ni+1.05+ atoms. In the fifth P3- site, P3- is bonded in a 9-coordinate geometry to two equivalent Ce3+ and seven Ni+1.05+ atoms.« less
