CeTeCl is Matlockite structured and crystallizes in the tetragonal P4/nmm 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 twelve equivalent Cl(1)Ce4 tetrahedra, corners with four equivalent Te(1)Ce5 trigonal bipyramids, edges with four equivalent Cl(1)Ce4 tetrahedra, and edges with eight equivalent Te(1)Ce5 trigonal bipyramids. Cl(1) is bonded to four equivalent Ce(1) atoms to form ClCe4 tetrahedra that share corners with four equivalent Cl(1)Ce4 tetrahedra, corners with twelve equivalent Te(1)Ce5 trigonal bipyramids, edges with four equivalent Cl(1)Ce4 tetrahedra, and edges with four equivalent Te(1)Ce5 trigonal bipyramids.
CeTeCl is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ce(1) is bonded in a 9-coordinate geometry to five equivalent Te(1) and four equivalent Cl(1) atoms. There is one shorter (3.27 Å) and four longer (3.33 Å) Ce(1)-Te(1) bond lengths. All Ce(1)-Cl(1) bond lengths are 3.00 Å. Te(1) is bonded to five equivalent Ce(1) atoms to form distorted TeCe5 trigonal bipyramids that share corners with twelve equivalent Cl(1)Ce4 tetrahedra, corners with four equivalent Te(1)Ce5 trigonal bipyramids, edges with four equivalent Cl(1)Ce4 tetrahedra, and edges with eight equivalent Te(1)Ce5 trigonal bipyramids. Cl(1) is bonded to four equivalent Ce(1) atoms to form ClCe4 tetrahedra that share corners with four equivalent Cl(1)Ce4 tetrahedra, corners with twelve equivalent Te(1)Ce5 trigonal bipyramids, edges with four equivalent Cl(1)Ce4 tetrahedra, and edges with four equivalent Te(1)Ce5 trigonal bipyramids.
