“…A series of different organic-inorganic materials (namely 3-ammoniumphenylsulfone selenate, 3-aminophenylsulfone, 3-ammoniumphenylsulfone dihydrogenphosphate phosphoric acid and bis(3-ammoniumphenyl)sulfone dinitrate) were rstly obtained with Mahroug et al in the period of 2011-2013. [29][30][31] By 2017, Kessentini et al had also conrmed the formation of an organic-inorganic 3,3 0 -(DDS)SnCl 6 hybrid system stabilized by different types of hydrogen bonding that are distinguished by their interesting electric properties. 32 Hence, we report here the synthesis, detailed crystallographic analysis, vibrational study, description of the thermal behavior and the optical properties of two new hybrid organicinorganic salts, namely 4,4 0 -diammoniumdiphenylsulfone sulfate (4,4 0 -DDS-S) and 3,3 0 -diammoniumdiphenylsulfone sulfate (3,3 0 -DDS-S).…”
