Abstract
Lösungen von BiI3 in THF oder Methanol reagieren mit MI (M = Li, Na) zu mehrkernigen Bismutiodokomplexen. Darstellung und Ergebnisse der Kristallstrukturanalyse von [Li(thf)4]2[Bi4I14(thf)2], [Li(thf)4]4[Bi5I19], [Na(thf)6]4[Bi6I22] und (Ph4P)4[Bi6I22] werden beschrieben. Die Anionen der vier Verbindungen bestehen aus kantenverknüpften BiI6‐ bzw. BiI5(thf)‐Oktaedern. In diesen Verbindungen liegen die Bi‐Atome in einer Ebene und werden verzerrt oktaedrisch von den verbrückenden und terminalen I‐Atomen bzw. THF‐Liganden koordiniert.[Li(thf)4]2[Bi4I14(thf)2]: Raumgruppe P1 (Nr. 2), a = 1 159,9(6), b = 1 364,6(7), c = 1 426,5(7) pm, α = 114,05(3), β = 90,01(3), γ = 100,62(3)°.[Li(thf)4]4[Bi5I19]: Raumgruppe P21/n (Nr. 14), a = 1 653,0(9), b = 4 350(4), c = 1 836,3(13) pm, β = 114,70(4)°.[Na(thf)6]4[Bi6I22]: Raumgruppe P21/n (Nr. 14), a = 1 636,4(3), b = 2 926,7(7), c = 1 845,8(4) pm, β = 111,42(2)°.(Ph4P)4[Bi6I22]: Raumgruppe P1 (Nr. 2), a = 1 368,6(7), b = 1 508,1(9), c = 1 684,9(8) pm, α = 98,28(4), β = 95,13(4), γ = 109,48(4)°.Keywords
