Ni3Sb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ni(1) is bonded to eight equivalent Ni(1) and four equivalent Sb(1) atoms to form NiNi8Sb4 cuboctahedra that share corners with twelve equivalent Ni(1)Ni8Sb4 cuboctahedra, edges with eight equivalent Sb(1)Ni12 cuboctahedra, edges with sixteen equivalent Ni(1)Ni8Sb4 cuboctahedra, faces with four equivalent Sb(1)Ni12 cuboctahedra, and faces with fourteen equivalent Ni(1)Ni8Sb4 cuboctahedra. Sb(1) is bonded to twelve equivalent Ni(1) atoms to form SbNi12 cuboctahedra that share corners with twelve equivalent Sb(1)Ni12 cuboctahedra, edges with twenty-four equivalent Ni(1)Ni8Sb4 cuboctahedra, faces with six equivalent Sb(1)Ni12 cuboctahedra, and faces with twelve equivalent Ni(1)Ni8Sb4 cuboctahedra.
