Synthesis and thermal decomposition of [Bi6O6(OH)2](NH2C6H4SO3)4

An investigation of the interaction of Bi(III) with an aqueous solution of sulfanilic acid at a higher temperature is performed. As a result, a new composition [Bi6O6(OH)2](NH2C6H4SO3)4 is precipitated. This Bi(III) complex is characterized by various methods: elemental analysis, DTA, TG–MS, DSC, FTIR, and powder X-ray diffraction. Based on the experimental results, X-ray diffraction indexation as well as thermal decomposition products of the compound are suggested.
