 Title    Tritelluride mit komplexierten Kationen: Darstellung und Kristallstruktur von [Ba(en) 3 ]Te 3 und [Ba(en) 4;5 ]Te 3 Tritellurides of Complex Cations: Synthesis and Crystal Structure of [Ba(en) 3 ]Te 3 and [Ba(en) 4 5 ]Te 3  
 Abstract    The two title compounds have been prepared by reaction of appropriate mixtures of the elements in ethylenediamine. The structures have been determined on the basis of single crystal data. [Ba(en) 3 ]Te 3 crystallizes in the monoclinic system, space group P2 (/c with a = 918.0(4), b — 1203.7(6), c = 1639.9(6) pm, ß = 93.4(1)°. In the structure there are bent tritelluride anions Te 3 2 ~ (bond lengths 273.9—278.5 pm, bond angle 105.7°). The Ba 2+ cations are six coordinate by the bidentate ligand ethylenediamine. [Ba(en) 4 5 ]Te 3 crystallizes in the monoclinic system, space group Cc with a = 1752.8(6), b = 938.9(4), c = 3041.7(8) pm, ß = 91.3(1)°. In this structure the bond lengths in the Te 3 2 ~ anions are shorter (272.1—273.1 pm, bond angles 110.9—112.2°). The cations are coordinated by four bidentate ligands, and are connected into pairs by a further ethylenediamine molecule. The resulting dinuclear [Ba(en) 4 ]en[Ba(en) 4 ] 4+ units have the Ba 2+ cations in CN 9.
