LaTeCl crystallizes in the orthorhombic Pnma space group. La(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 La(1) atoms to form distorted TeLa5 trigonal bipyramids that share corners with eight equivalent Cl(1)La4 tetrahedra, corners with eight equivalent Te(1)La5 trigonal bipyramids, edges with six equivalent Cl(1)La4 tetrahedra, and edges with six equivalent Te(1)La5 trigonal bipyramids. Cl(1) is bonded to four equivalent La(1) atoms to form ClLa4 tetrahedra that share corners with eight equivalent Cl(1)La4 tetrahedra, corners with eight equivalent Te(1)La5 trigonal bipyramids, edges with two equivalent Cl(1)La4 tetrahedra, and edges with six equivalent Te(1)La5 trigonal bipyramids.
LaTeCl crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 9-coordinate geometry to five equivalent Te(1) and four equivalent Cl(1) atoms. There are two shorter (3.32 Å) and three longer (3.36 Å) La(1)-Te(1) bond lengths. There are a spread of La(1)-Cl(1) bond distances ranging from 3.01-3.10 Å. Te(1) is bonded to five equivalent La(1) atoms to form distorted TeLa5 trigonal bipyramids that share corners with eight equivalent Cl(1)La4 tetrahedra, corners with eight equivalent Te(1)La5 trigonal bipyramids, edges with six equivalent Cl(1)La4 tetrahedra, and edges with six equivalent Te(1)La5 trigonal bipyramids. Cl(1) is bonded to four equivalent La(1) atoms to form ClLa4 tetrahedra that share corners with eight equivalent Cl(1)La4 tetrahedra, corners with eight equivalent Te(1)La5 trigonal bipyramids, edges with two equivalent Cl(1)La4 tetrahedra, and edges with six equivalent Te(1)La5 trigonal bipyramids.
