The structure described by Er2Co2Ga crystallizes in the orthorhombic Immm space group. Er(1) is bonded in a 10-coordinate geometry to six equivalent Co(1) and four equivalent Ga(1) atoms. Co(1) is bonded in a 9-coordinate geometry to six equivalent Er(1), one Co(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to eight equivalent Er(1) and four equivalent Co(1) atoms to form a mixture of face and edge-sharing GaEr8Co4 cuboctahedra. is represented by the CIF file [CIF]
