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) A, b=19.78(1) A, c=8.795(8) A, γ = 94.33(4)o as well as a cell volume = 5424.21 A3 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.enArticle
