Materials Data on Ce2ZnNi2 by Materials Project

Abstract

Ce2Ni2Zn crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Ce is bonded in a 10-coordinate geometry to six equivalent Ni and four equivalent Zn atoms. There are two shorter (2.75 Å) and four longer (2.99 Å) Ce–Ni bond lengths. There are two shorter (3.15 Å) and two longer (3.21 Å) Ce–Zn bond lengths. Ni is bonded in a 9-coordinate geometry to six equivalent Ce, one Ni, and two equivalent Zn atoms. The Ni–Ni bond length is 2.55 Å. Both Ni–Zn bond lengths are 2.64 Å. Zn is bonded to eight equivalent Ce and four equivalent Ni atoms to form a mixture of distorted edge and face-sharing ZnCe8Ni4 cuboctahedra.
