The crystal structure described by CeOs2SiC crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 4-coordinate geometry to three equivalent Si(1) and four equivalent C(1) atoms. Os(1) is bonded in a 4-coordinate geometry to three equivalent Si(1) and one C(1) atom. Si(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent Os(1) atoms. C(1) is bonded to four equivalent Ce(1) and two equivalent Os(1) atoms to form a mixture of corner and edge-sharing CCe4Os2 octahedra. The corner-sharing octahedral tilt angles are 25°. is represented by the CIF file [CIF]
