The structure described by Fe3Ni is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to eight equivalent Fe(1) and four equivalent Ni(1) atoms to form FeFe8Ni4 cuboctahedra that share corners with twelve equivalent Fe(1)Fe8Ni4 cuboctahedra, edges with eight equivalent Ni(1)Fe12 cuboctahedra, edges with sixteen equivalent Fe(1)Fe8Ni4 cuboctahedra, faces with four equivalent Ni(1)Fe12 cuboctahedra, and faces with fourteen equivalent Fe(1)Fe8Ni4 cuboctahedra. Ni(1) is bonded to twelve equivalent Fe(1) atoms to form NiFe12 cuboctahedra that share corners with twelve equivalent Ni(1)Fe12 cuboctahedra, edges with twenty-four equivalent Fe(1)Fe8Ni4 cuboctahedra, faces with six equivalent Ni(1)Fe12 cuboctahedra, and faces with twelve equivalent Fe(1)Fe8Ni4 cuboctahedra. is represented by the CIF card [CIF]
