Abstract

The Bismuth Hydrogen Sulfate [Bi 2(SO4)2(dmso)8](HSO4)2. -[Bi 2(SO4)2(dmso)8](HSO4)2 is prepared by the reaction of basic [Bi 6O4(OH)4(NO3)6]·H2O with either thiosalicylic acid or H2SO4 in DMSO (80 C, 7 h, slow diffusion of Me2CO into the solution). The formation of sulfate ions is observed in the presence of either Bi 3+ or [Bi6O4(OH)4] 6+ indicating Bi-induced oxidation of thiosalicylic acid. The compound crystallizes in the triclinic space group P1 (Z = 1, single crystal XRD) and is composed of alternating layers of [Bi 2(SO4)2(dmso)8] 2+ cations and anions. Within the anionic layers, two adjacent are linked to each other by hydrogen bridges. IR spectra and thermal decomposition studies reveal the formation of Bi 2O(SO4)2 and Bi2O2(SO4) as intermediates and Bi28O32(SO4)10 as the final product. -(WROBEL, L.; MIERSCH, L.; SCHLESINGER, M.; RUEFFER, T.; LANG, H.; MEHRING*, M.; Z.
