Thermal decomposition of DMSO or DMF solvates: an advanced method for obtaining new hybrid bismuth(iii) halides

Abstract

Eight new solvates of 1,1′-(1,4-phenylenebis(methylene))bis(1-pyridinium) hybrid halobismuthates were obtained from dimethyl sulfoxide (DMSO) and dimethylformamide (DMF) solutions and structurally characterized. The thermal stability of the solvates was studied using TGA/DSC methods, and the appropriate conditions for the solvent molecule loss were defined. As a result, five new hybrid halobismuthates were prepared by the thermal decomposition of the obtained solvates. Based on the synchrotron powder X-ray diffraction data, the structure of the anionic part of the crystal products produced by the thermal decomposition of solvates was determined. The optical band gap values were defined for all the prepared products. The proposed method for obtaining new hybrid halobismuthates is prospective for the synthesis of compounds, which cannot be prepared from solutions.
