Two novel polytellurite-chlorides Pb5Cu2(Te4O11)Cl8 (1) and CdCu2(Te3O8)Cl2 (2) were obtained by a chemical vapor transport (CVT-reactions) reactions. The structure of 1 is based on [Pb5Cu2(Te4O11)]8+ one-dimensional blocks with full and partially occupied Cl sites around. The structure of 2 can be described as being formed by two types of one-dimensional units formed by Cd,Cu-centered polyhedra and TeO3, TeO4 pyramids sharing via common O atoms into electroneutral [CdCu2(Te3O8)Cl2]0 sheets. Obtaining of novel polytellurite-chlorides demonstrates effectiveness of CVT techniques for preparation of different tellurite-based complex layered materials.
