Materials Data on Er2GaCo2 by Materials Project

Abstract

Er2Co2Ga crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Er is bonded in a 10-coordinate geometry to six equivalent Co and four equivalent Ga atoms. There are two shorter (2.88 Å) and four longer (2.89 Å) Er–Co bond lengths. There are two shorter (3.16 Å) and two longer (3.21 Å) Er–Ga bond lengths. Co is bonded in a 9-coordinate geometry to six equivalent Er, one Co, and two equivalent Ga atoms. The Co–Co bond length is 2.34 Å. Both Co–Ga bond lengths are 2.54 Å. Ga is bonded to eight equivalent Er and four equivalent Co atoms to form a mixture of face and edge-sharing GaEr8Co4 cuboctahedra.
