Title: Materials Data on Ce2Zn2Ni5 by Materials Project

Abstract

Ce2Ni5Zn2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are six inequivalent Ce sites. In the first Ce site, Ce is bonded in a 12-coordinate geometry to nine equivalent Ni and three equivalent Zn atoms. There are six shorter (2.84 Å) and three longer (3.23 Å) Ce–Ni bond lengths. All Ce–Zn bond lengths are 3.01 Å. In the second Ce site, Ce is bonded in a distorted hexagonal planar geometry to twelve Ni and six Zn atoms. There are six shorter (2.91 Å) and six longer (3.21 Å) Ce–Ni bond lengths. All Ce–Zn bond lengths are 3.30 Å. In the third Ce site, Ce is bonded in a distorted hexagonal planar geometry to twelve Ni and six Zn atoms. There are six shorter (2.91 Å) and six longer (3.21 Å) Ce–Ni bond lengths. All Ce–Zn bond lengths are 3.30 Å. In the fourth Ce site, Ce is bonded in a distorted hexagonal planar geometry to twelve Ni and six Zn atoms. There are six shorter (2.91 Å) and six longer (3.21 Å) Ce–Ni bond lengths. All Ce–Zn bond lengths are 3.30 Å. In the fifth Ce site, Ce is bonded in a distorted hexagonal planar geometrymore » to twelve Ni and six Zn atoms. There are six shorter (2.91 Å) and six longer (3.21 Å) Ce–Ni bond lengths.

There are two shorter (2.55 Å) and two longer (2.56 Å) Zn–Ni bond lengths. Both Zn–Zn bond lengths are 2.52 Å. In the third Zn site, Zn is bonded to four Ce, four Ni, and four Zn atoms to form distorted ZnCe4Zn4Ni4 cuboctahedra that share corners with four equivalent ZnCe4Zn4Ni4 cuboctahedra, corners with twelve equivalent NiCe5ZnNi6 cuboctahedra, edges with two equivalent ZnCe4Zn4Ni4 cuboctahedra, edges with eight equivalent NiCe5ZnNi6 cuboctahedra, faces with two equivalent NiCe5ZnNi6 cuboctahedra, and faces with eight ZnCe4Zn4Ni4 cuboctahedra. There are two shorter (2.55 Å) and two longer (2.56 Å) Zn–Ni bond lengths. In the fourth Zn site, Zn is bonded to six equivalent Ce and six equivalent Ni atoms to form ZnCe6Ni6 cuboctahedra that share corners with twelve equivalent NiCe5ZnNi6 cuboctahedra, edges with six equivalent ZnCe6Ni6 cuboctahedra, and faces with eighteen equivalent NiCe5ZnNi6 cuboctahedra. In the fifth Zn site, Zn is bonded to four Ce, four Ni, and four Zn atoms to form distorted ZnCe4Zn4Ni4 cuboctahedra that share corners with four equivalent ZnCe4Zn4Ni4 cuboctahedra, corners with twelve equivalent NiCe5ZnNi6 cuboctahedra, edges with two equivalent ZnCe4Zn4Ni4 cuboctahedra, edges with eight equivalent NiCe5ZnNi6 cuboctahedra, faces with two equivalent NiCe5ZnNi6 cuboctahedra, and faces with eight ZnCe4Zn4Ni4 cuboctahedra.
