Synthesis and Crystal Structure of [Li(thf)4]2[Bi4I14(thf)2], [Li(thf)4]4[Bi5I19], and (Ph4P)4[Bi6I22]Solutions of BiI3 in THF or methanol react with MI (M = Li, Na) to form polynuclear iodo complexes of bismuth. The syntheses and results of X-ray structure analyses of compounds [Li(thf)4]2[Bi4I14(thf)2], [Li(thf)4]4[Bi5I19], [Na(thf)6]4[Bi6I22] and (Ph4P)4[Bi6I22] are described. The anions of these compounds consist of edge-sharing BiI6 and BiI5(thf) octahedra. The Bi atoms lie in a plane and are coordinated by bridging and terminal I atoms and by THF ligands in a distorted octahedral fashion.[Li(thf)4]2[Bi4I14(thf)2]: Space group P1 (No. 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]: Space group P21/n (No. 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]: Space group P21/n (No. 14), a = 1 636.4(3), b = 2 926.7(7), c = 1 845.8(4) pm, β = 111.42(2)°.(Ph4P)4[Bi6I22]: Space group P1 (No. 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)°.
Notes:
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)°.
