DyCeC4 crystallizes in the tetragonal P4/mmm space group. Dy(1) is bonded in a distorted q4 geometry to two equivalent C(2) and eight equivalent C(1) atoms. Ce(1) is bonded in a distorted q4 geometry to two equivalent C(1) and eight equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to four equivalent Dy(1), one Ce(1), and one C(1) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to one Dy(1), four equivalent Ce(1), and one C(2) atom.
