Abstract
2-Amino-5-methyl-1,3,4-thiadiazole, 2-amino-5-methyl-3H-1,3,4-thiadiazolium bromide [(amtzH)(amtz)Br] and bis(2,5-diamino-3H-1,3,4-thiadiazolium) sulfate [(a2tzH)2SO4] were prepd. and characterized by x-ray structural anal. and IR spectroscopy. The crystals of (amtzH)(amtz)Br are monoclinic. Its asym. unit contains one protonated amtzH cation, one neutral amtz mol., and one bromide ion. The crystals of (a2tzH)2SO4 are monoclinic. The structure is built up of one crystallog. independent a2tzH cation and one half sulfate ion with crystallog. dictated twofold symmetry.
