Strukturuntersuchungen an einigen Iodoantimonat- und Iodobismutat-AnionenDie Reaktion zwischen BiI3 und zwei Äquivalenten dmpu (dmpu = N,N′-Dimethylpropylharnstoff) in THF oder Toluol ergibt dunkelrote Kristalle von [Bi(dmpu)6] · [Bi3I12]. Nach röntgenographischer Charakterisierung besteht die Verbindung aus oktaedrischen [Bi(dmpu)6]3+-Kationen und [Bi3I12]3--Anionen, beide mit der Symmetrie 3. Die analoge Reaktion mit SbI3 ergibt orange Kristalle von [C5NH6]2[H(dmpu)2][Sb2I9], wahrscheinlich ein Hydrolyseprodukt. Die röntgenographische Charakterisierung ergab flächenverknüpfte dioktaedrische [Sb2I9]3--Anionen mit zwei Pyridinium und einem [H(dmpu)2]+-Kation.[CH2=C(C6H4-4-NO2)CH2NMe3]I und ein Äquivalent SbI3 ergibt den orangen, kristallinen Komplex [CH2=C(C6H4-4-NO2)CH2NMe3]3[Sb2I9] mit flächenverknüpften dioktaedrischen [Sb2I9]3--Anionen.[CH2=C(C6H4-4-NO2)CH2NMe3]I und vier Äquivalente BiI3 ergeben [CH2=C(C6H4-4-NO2)CH2NMe3]3[Bi3I12] mit dem zum [Bi(dmpu)6][Bi3I12] analogen Anion.[CH3(CH2)2COS(CH2)2NMe3]I mit vier Äquivalenten SbI3 ergeben orange Kristalle von [CH3(CH2)2COS(CH2)2NMe3]4 · [Sb8I28], die nach Röntgenstrukturuntersuchungen einen neuen Strukturtyp von [E8X28]4--Anionen (E = As, Sb, Bi; X = Halogen) darstellen.
Notes:
The reaction between BiI3 and two equivalents of dmpu (dmpu = N,N′-dimethylpropylene urea) in thf (tetrahydrofuran) or toluene affords dark red crystals of the complex [Bi(dmpu)6][Bi3I12] which was characterised by X-ray crystallography and consists of octahedral [Bi(dmpu)6]3+ cations and [Bi3I12]3- anions both with 3 symmetry. An analogous reaction between SbI3 and dmpu afforded orange crystals of what is probably a hydrolysis product, [C5NH6]2[H(dmpu)2][Sb2I9], which was also characterised by X-ray crystallography and contains a face-shared bioctahedral [Sb2I9]3- anion with two pyridinium cations and a hydrogen bonded [H(dmpu)2]+ cation. [CH2=C(C6H4-4-NO2)CH2NMe3]I and one equivalent of SbI3 afforded the orange crystalline complex [CH2=C(C6H4-4-NO2)CH2NMe3]3[Sb2I9] an X-ray crystallographic study of which revealed a face-shared bioctahedral [Sb2I9]3- anion similar to that present in [C5NH6]2[H(dmpu)2][Sb2I9]. Four equivalents of BiI3 and [CH2=C(C6H4-4-NO2)CH2NMe3]I afforded the complex [CH2=C(C6H4-4-NO2)CH2NMe3]3[Bi3I12], the [Bi3I12]3- anion being essentially identical to that encountered in [Bi(dmpu)6][Bi3I12]. [CH3(CH2)2COS(CH2)2NMe3]I and four equivalents of SbI3 yielded orange crystals of the complex [CH3(CH2)2COS(CH2)2NMe3]4[Sb8I28] which was also characterised by X-ray crystallography and shown to contain a new structural type of [E8X28]4- anion (E = As, Sb, Bi; X = halide).
