Synthesis and Crystal Structure of Te6[MCl6] (M: Zr, Hf), Containing a Polymeric
Chalcogen Cation (Te2+
6 )n. — The title compounds are prepared in nearly quantitative yield by chemical vapor transport reaction of Te and ZrCl4 or HfCl4 (evacuated
glass tube, 220→200 °C, 3 weeks). Te6[ZrCl6] and Te 6[HfCl 6] are isotypic and crystallize in the orthorhombic space group Pbcm with Z = 4 (single crystal XRD). The struc1
2+
ture consists of discrete M Cl26 octahedra and polymeric ∞ [Te6 ] chains formed by
five-membered rings which are connected via single Te atoms. — (BAUMANN, A.;
