Synthesis and thermal decomposition of [Bi6O4(OH)4](NH2SO3)6

The interaction of Bi(III) with aqueous solution of sulfamic acid is investigated, and a new compound with the following composition [Bi6O4(OH)4](NH2SO3)6 is derived. The substance obtained is characterized by various methods: elemental analysis, DTA, TG, FTIR and X-ray diffraction. Based on the experimental results, a mechanism of thermal decomposition of the newly synthesized compound is proposed.
