Abstract: 

Single crystals of (TeCl3)2MoCl6 and β-(TeCl3)2ReCl6 are obtained by the reactions of TeCl4 with MoCl4 at 195 °C and of TeCl4 / Te with ReCl5 at 150 °C, respectively. The com pounds form dark-red moisture sensitive crystals. The crystal structure determinations show, that both crystallize isotypically ( rhombohedral, space group R3̄, (TeCl3)2MoCl6: a = 1116,9(1), c = 3539,5(5) pm. 1966 unique reflections for 69 parameters, final R = 0.058; β-(TeCl3)2 ReCl6: a = 1113,3(3), c = 3546(2) pm. 1653 unique reflections for 70 parameters, final R = 0.034). The structures consist of octahedral MCl62- anions (with M=Mo,Re) and pyramidal TeCl3+ cations. The ions are interconnected through long Te-Cl bridges (291,1- 295,6 pm) to give distorted TeCl6 octahedra. MCl6 and TeCl6 units are connected via edges and corners, resulting in a complex layer structure with layers parallel to the ab-plane. In the previously reported a-form of (TeCl3)2ReCl6, only connections via corners are observed.
