During attempts to achieve inter-action between 2-amino-5-ethyl-1,3,4-thia-diazole with oxalyl chloride and 5-mercapto-3-phenyl-1,3,4-thia-diazol-2-thione with various diacid anhydrides, we obtained two co-crystals (organic salts), namely, 2-amino-5-ethyl-1,3,4-thia-diazol-3-ium hemioxalate, CHNS·0.5CO , (I), and 4-(di-methyl-amino)-pyridin-1-ium 4-phenyl-5-sulfanyl-idene-4,5-di-hydro-1,3,4-thia-diazole-2-thiol-ate, CHN ·CHNS , (II). Both solids were investigated by single-crystal X-ray diffraction and by Hirshfeld surface analysis.
