Description:
The reaction of the basic bismuth nitrate [Bi 6 O 4 (OH) 4 (NO 3 ) 6 ] · H 2 O with either thiosalicylic acid or sulfuric acid gave the novel bismuth hydrogen sulfate [Bi 2 (SO 4 ) 2 (dmso) 8 ](HSO 4 ) 2 ( 1 ) (DMSO = dimethyl sulfoxide). The formation of sulfate ions is observed in the presence of either Bi 3+ or [Bi 6 O 4 (OH) 4 ] 6+ indicating bismuth-induced oxidation of thiosalicylic acid. Compound 1 was characterized by elemental analysis, infrared spectroscopy, thermal analysis (TGA), and temperature dependent in situ X-ray powder diffraction. Crystals suitable for single crystal structure analysis were obtained from a DMSO/acetone solution. The title compound 1 crystallizes in the triclinic space group P with the following lattice parameters: a = 9.5240(4) Å, b = 9.9535(4) Å, c = 12.6620(5) Å, α = 109.943(4)°, β = 93.952(3)°, γ = 102.868(3)°, V = 1086.17(8) Å 3 , and Z = 1. Analysis of the thermally induced decomposition revealed the formation of Bi 2 O(SO 4 ) 2 and Bi 2 O 2 (SO 4 ) as intermediate products and Bi 28 O 32 (SO 4 ) 10 as final product.
