Materials Data on Er3(GaNi3)2 by Materials Project

Abstract

Er3(Ni3Ga)2 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Er is bonded in a 12-coordinate geometry to eight equivalent Ni and four equivalent Ga atoms. There are four shorter (2.73 Å) and four longer (3.02 Å) Er–Ni bond lengths. All Er–Ga bond lengths are 3.14 Å. Ni is bonded in a 12-coordinate geometry to four equivalent Er, six equivalent Ni, and two equivalent Ga atoms. There are four shorter (2.55 Å) and two longer (2.84 Å) Ni–Ni bond lengths. Both Ni–Ga bond lengths are 2.47 Å. Ga is bonded to six equivalent Er and six equivalent Ni atoms to form a mixture of corner and face-sharing GaEr6Ni6 cuboctahedra.
