CeMo2Si2C crystallizes in the tetragonal P4/mmm space group. Ce(1) is bonded in a distorted linear geometry to eight equivalent Si(1) and two equivalent C(1) atoms. Mo(1) is bonded to four equivalent Si(1) and two equivalent C(1) atoms to form a mixture of distorted edge, corner, and face-sharing MoSi4C2 octahedra. The corner-sharing octahedra are not tilted. Si(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), four equivalent Mo(1), and one Si(1) atom. C(1) is bonded to two equivalent Ce(1) and four equivalent Mo(1) atoms to form corner-sharing CCe2Mo4 octahedra. The corner-sharing octahedra are not tilted.
