Materials Data on Tm2GaCo2 by Materials Project

Abstract

Tm2Co2Ga crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Tm is bonded in a 10-coordinate geometry to six equivalent Co and four equivalent Ga atoms. There are two shorter (2.86 Å) and four longer (2.87 Å) Tm–Co bond lengths. There are two shorter (3.14 Å) and two longer (3.19 Å) Tm–Ga bond lengths. Co is bonded in a 9-coordinate geometry to six equivalent Tm, one Co, and two equivalent Ga atoms. The Co–Co bond length is 2.35 Å. Both Co–Ga bond lengths are 2.52 Å. Ga is bonded to eight equivalent Tm and four equivalent Co atoms to form a mixture of edge and face-sharing GaTm8Co4 cuboctahedra.
