The structure described by UCe4C10 crystallizes in the orthorhombic Immm space group. U(1) is bonded in a distorted q4 geometry to two equivalent C(3) and eight equivalent C(1) atoms. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 10-coordinate geometry to two equivalent C(1), four equivalent C(2), and four equivalent C(3) atoms. In the second Ce site, Ce(2) is bonded in a 10-coordinate geometry to four equivalent C(1) and six equivalent C(2) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to two equivalent U(1), one Ce(1), two equivalent Ce(2), and one C(1) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to two equivalent Ce(1), three equivalent Ce(2), and one C(2) atom. In the third C site, C(3) is bonded in a 6-coordinate geometry to one U(1), four equivalent Ce(1), and one C(3) atom. is represented by the CIF file [CIF]
