Synthesis of new complex [Bi6O6(OH)2](ClC6H4SO3)4 and investigation of its thermal decomposition

Abstract

A new [Bi6O6(OH)2](ClC6H4SO3)4 complex is synthesized through a reaction of Bi2O3 with aqueous 4-chlorobenzenesulfonic acid at elevated temperature. The product composition is elucidated by elemental analysis, ICP-OES and FTIR techniques. By means of XRD analysis, the compound’s indexation, monoclinic P2(3) space group and unit cell parameters: a=31.25(3) Å, b=19.78(1) Å, c=8.795(8) Å, γ = 94.33(4)o as well as a cell volume = 5424.21 Å3 are determined. Based on DTA-TG technique, three specific temperatures aimed at studying product’s thermal decomposition are determined. The compositions of solid residues after isothermal heating are proved following the XRD and FTIR data.
