The structure described by Tb3Ni6Al2 crystallizes in the cubic Im-3m space group. Tb(1) is bonded in a 12-coordinate geometry to eight equivalent Ni(1) and four equivalent Al(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to four equivalent Tb(1), four equivalent Ni(1), and two equivalent Al(1) atoms. Al(1) is bonded to six equivalent Tb(1) and six equivalent Ni(1) atoms to form a mixture of distorted face and corner-sharing AlTb6Ni6 cuboctahedra. is represented by the CIF card [CIF]
