Crystal and molecular structure of (α-naphthyl)TeI3

(α-Naphthyl-Te)2 reacts with iodine in toluene to give deep brown crystals of (α-naphthyl)TeI3. The structure of the new organotellurium trihalide has been studied by means of single crystal X-ray diffractometry. (α-Naphthyl)TeI3 crystallizes in the monoclinic space group P21/c. The primary coordination sphere about the Te atom is bisphenoidal. The secondary bonds among the heavy atoms hold the (α-naphthyl)TeI3 molecules into chains along the lattice; the TeI primary bonds show additionally different lengths. The compound can be considered as a supramolecular array comprised of tectonic charge-transfer complexes.
