Lu2Cu2In crystallizes in the tetragonal P4/mbm space group. Lu(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent In(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Lu(1), one Cu(1), and two equivalent In(1) atoms. In(1) is bonded to eight equivalent Lu(1) and four equivalent Cu(1) atoms to form a mixture of face and corner-sharing InLu8Cu4 cuboctahedra.
Lu2Cu2In crystallizes in the tetragonal P4/mbm space group. Lu(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent In(1) atoms. There are two shorter (2.83 Å) and four longer (2.84 Å) Lu(1)-Cu(1) bond lengths. All Lu(1)-In(1) bond lengths are 3.28 Å. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Lu(1), one Cu(1), and two equivalent In(1) atoms. The Cu(1)-Cu(1) bond length is 2.53 Å. Both Cu(1)-In(1) bond lengths are 2.90 Å. In(1) is bonded to eight equivalent Lu(1) and four equivalent Cu(1) atoms to form a mixture of face and corner-sharing InLu8Cu4 cuboctahedra.
