The material described by CeYC4 crystallizes in the monoclinic C2/m space group. Ce(1) is bonded in a distorted q4 geometry to four equivalent C(1) and six equivalent C(2) atoms. Y(1) is bonded in a 10-coordinate geometry to four equivalent C(2) and six equivalent C(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to two equivalent Ce(1), three equivalent Y(1), and one C(2) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to three equivalent Ce(1), two equivalent Y(1), and one C(1) atom. is represented by the CIF file [CIF]
