The material described by Er2Ni2Ga crystallizes in the orthorhombic Immm space group. Er(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Ga(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Er(1), one Ni(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to eight equivalent Er(1) and four equivalent Ni(1) atoms to form a mixture of edge and face-sharing GaEr8Ni4 cuboctahedra. is represented by the CIF card [CIF]
