SrTeCl crystallizes in the trigonal R3m space group. Sr(1) is bonded in a distorted single-bond geometry to one Te(1) and three equivalent Cl(1) atoms. The Sr(1)-Te(1) bond length is 1.29 Å. All Sr(1)-Cl(1) bond lengths are 3.15 Å. Te(1) is bonded in a distorted linear geometry to one Sr(1) and one Cl(1) atom. The Te(1)-Cl(1) bond length is 2.57 Å. Cl(1) is bonded to three equivalent Sr(1) and one Te(1) atom to form corner-sharing ClSr3Te trigonal pyramids.
