Materials Data on Nd2GaNi2 by Materials Project

Abstract

Nd2Ni2Ga crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Nd is bonded in a 10-coordinate geometry to six equivalent Ni and four equivalent Ga atoms. There are two shorter (2.94 Å) and four longer (3.02 Å) Nd–Ni bond lengths. There are two shorter (3.28 Å) and two longer (3.29 Å) Nd–Ga bond lengths. Ni is bonded in a 9-coordinate geometry to six equivalent Nd, one Ni, and two equivalent Ga atoms. The Ni–Ni bond length is 2.47 Å. Both Ni–Ga bond lengths are 2.63 Å. Ga is bonded to eight equivalent Nd and four equivalent Ni atoms to form a mixture of edge and face-sharing GaNd8Ni4 cuboctahedra.
