U2Co2Al crystallizes in the tetragonal P4/mbm space group. U(1) is bonded in a 6-coordinate geometry to six equivalent Co(1) and four equivalent Al(1) atoms. Co(1) is bonded in a 8-coordinate geometry to six equivalent U(1) and two equivalent Al(1) atoms. Al(1) is bonded to eight equivalent U(1) and four equivalent Co(1) atoms to form a mixture of face and corner-sharing AlU8Co4 cuboctahedra.
U2Co2Al crystallizes in the tetragonal P4/mbm space group. U(1) is bonded in a 6-coordinate geometry to six equivalent Co(1) and four equivalent Al(1) atoms. There are two shorter (2.56 Å) and four longer (2.78 Å) U(1)-Co(1) bond lengths. All U(1)-Al(1) bond lengths are 3.13 Å. Co(1) is bonded in a 8-coordinate geometry to six equivalent U(1) and two equivalent Al(1) atoms. Both Co(1)-Al(1) bond lengths are 2.75 Å. Al(1) is bonded to eight equivalent U(1) and four equivalent Co(1) atoms to form a mixture of face and corner-sharing AlU8Co4 cuboctahedra.
