Materials Data on Tb3(GaNi3)2 by Materials Project

Abstract

Tb3(Ni3Ga)2 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Tb is bonded in a 12-coordinate geometry to eight equivalent Ni and four equivalent Ga atoms. There are four shorter (2.78 Å) and four longer (3.05 Å) Tb–Ni bond lengths. All Tb–Ga bond lengths are 3.18 Å. Ni is bonded in a 12-coordinate geometry to four equivalent Tb, six equivalent Ni, and two equivalent Ga atoms. There are four shorter (2.58 Å) and two longer (2.90 Å) Ni–Ni bond lengths. Both Ni–Ga bond lengths are 2.49 Å. Ga is bonded to six equivalent Tb and six equivalent Ni atoms to form a mixture of face and corner-sharing GaTb6Ni6 cuboctahedra.
