The compound described by CeNiZn2 is Uranium Silicide-derived structured and crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded to four equivalent Ni(1) and eight equivalent Zn(1) atoms to form distorted CeZn8Ni4 cuboctahedra that share corners with twelve equivalent Ce(1)Zn8Ni4 cuboctahedra, edges with sixteen equivalent Zn(1)Ce4Zn4Ni4 cuboctahedra, faces with six equivalent Ce(1)Zn8Ni4 cuboctahedra, and faces with eight equivalent Zn(1)Ce4Zn4Ni4 cuboctahedra. Ni(1) is bonded in a square co-planar geometry to four equivalent Ce(1) and eight equivalent Zn(1) atoms. Zn(1) is bonded to four equivalent Ce(1), four equivalent Ni(1), and four equivalent Zn(1) atoms to form ZnCe4Zn4Ni4 cuboctahedra that share corners with twelve equivalent Zn(1)Ce4Zn4Ni4 cuboctahedra, edges with eight equivalent Ce(1)Zn8Ni4 cuboctahedra, edges with eight equivalent Zn(1)Ce4Zn4Ni4 cuboctahedra, faces with four equivalent Ce(1)Zn8Ni4 cuboctahedra, and faces with ten equivalent Zn(1)Ce4Zn4Ni4 cuboctahedra. is represented by the CIF file [CIF]
