Ni3Bi 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 Bi(1) atoms to form NiNi8Bi4 cuboctahedra that share corners with twelve equivalent Ni(1)Ni8Bi4 cuboctahedra, edges with eight equivalent Bi(1)Ni12 cuboctahedra, edges with sixteen equivalent Ni(1)Ni8Bi4 cuboctahedra, faces with four equivalent Bi(1)Ni12 cuboctahedra, and faces with fourteen equivalent Ni(1)Ni8Bi4 cuboctahedra. Bi(1) is bonded to twelve equivalent Ni(1) atoms to form BiNi12 cuboctahedra that share corners with twelve equivalent Bi(1)Ni12 cuboctahedra, edges with twenty-four equivalent Ni(1)Ni8Bi4 cuboctahedra, faces with six equivalent Bi(1)Ni12 cuboctahedra, and faces with twelve equivalent Ni(1)Ni8Bi4 cuboctahedra.
