Abstract:
The reaction of SeBr4 and AlBr3 in a closed glass ampoule at 150 degrees C yields quantitatively SeBr3[AlBr4] in form of yellow moisture sensitive crystals. From Te, two equivalents of I-2 and AlI4 one obtains TeI3[AlI4] in form of dark red, moisture sensitive crystals. Both compounds crystallize monoclinic in the space group Pc (SeBr3[AlBr4]: a = 670.7(7)pm, b = 663.9(5) pm, c = 1428.6(2)pm, beta = 101.21(9)degrees, TeI3[AlI4]: a = 731.9(1) pm, b = 730.8(1) pm, c = 1565.5(3)pm, beta = 102.01(2)degrees). They are isotypic and have the SCl3[AlCl4] structure type. The structures are built of tetrahedral AlX(4) ions and of pyramidal EX(3)(+) ions (E = S, Se, Te; X = Cl, Br, I). The chalcogen atoms are additionally coordinated by halogen atoms of surrounding AlX(4)(-) ions, corresponding to a strongly distorted octahedral coordination EX(3+3).
