The title compounds,C_(12)H_(10)N_3O_7SC1(Ⅰ)and C_(15)H_(27)NO_3S(Ⅱ),crystallize in the monoclinic system,space group P2_1/c with a=7.3995(1),b=27.8489(6),c=9.8246(2)A,β=131.349(1)°,V=1519.82(5)A~3,Z=4,F(000)=768,R_(int)=0.033 and S=1.03 forⅠ,and in the orthorhombic system,space group Pbca with a=8.6227(1),b=16.1480(4),c=23.8774(6)A,V=3324.67(12)A~3,Z=8,F(000)=1312,R_(int)=0.024 and S=1.04 forⅡ.We have devised a convenient procedure for the synthesis of fused organic salts resulting from 1:1 proton-transfer,using an amine and a derivative of benzenesulfonic acid.The synthesized salts have a number of applications ranging from their consumption as eco-friendly solvents and catalysts in organic syntheses,to being used as efficient precursors for the production of sulfa drugs.Structures of compounds 3-chloroanilinium2,4-dinitrobenzenesulfonate(CA-DNBS)and triethylaminium 2,4,6-trimethylbenzenesulfonate(TEA-TMBS)were determined by single-crystal X-ray diffraction studies and infrared spectroscopy.
