The crystal structure described by La2Ni2Zn crystallizes in the orthorhombic Immm space group. La(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Zn(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to six equivalent La(1), two equivalent Ni(1), and two equivalent Zn(1) atoms. Zn(1) is bonded to eight equivalent La(1) and four equivalent Ni(1) atoms to form a mixture of distorted edge and face-sharing ZnLa8Ni4 cuboctahedra. is represented by the CIF card [CIF]
