CeTeCl crystallizes in the orthorhombic Pnma space group. Ce(1) is bonded in a 9-coordinate geometry to five equivalent Te(1) and four equivalent Cl(1) atoms. Te(1) is bonded to five equivalent Ce(1) atoms to form distorted TeCe5 trigonal bipyramids that share corners with eight equivalent Cl(1)Ce4 tetrahedra, corners with eight equivalent Te(1)Ce5 trigonal bipyramids, edges with six equivalent Cl(1)Ce4 tetrahedra, and edges with six equivalent Te(1)Ce5 trigonal bipyramids. Cl(1) is bonded to four equivalent Ce(1) atoms to form ClCe4 tetrahedra that share corners with eight equivalent Cl(1)Ce4 tetrahedra, corners with eight equivalent Te(1)Ce5 trigonal bipyramids, edges with two equivalent Cl(1)Ce4 tetrahedra, and edges with six equivalent Te(1)Ce5 trigonal bipyramids.
