Abstract

2-amino-5-methyl-1,3,4-thiadiazole, 2-arnino-5-methyl-3H-1,3,4-thiadiazolium bromide[(amtzH)(amtz)Br] and bis (2,5-diamino-3H-1,3,4-thiadiazolium) sulphate [(a 2 tzH)2SO4] were prepared and characterized by means of X-ray structural analysis and infrared spectroscopy. The crystals of (amtzH) (amtz)Br are monoclinic; space groupP21/c, witha=7.620(2),b=17.166(2),c=9.411(2)Å,β=96.34(2)°, andZ=4. Its asymmetric unit contains one protonatedamtzH cation, one neutralamtz molecule, and one bromide ion. The crystals of (a 2 tzH)2SO4 are monoclinic; space groupC2/c, witha=11.797(2),b=9.213(2),c=10.720(2)Å,β=91.30(2)°, andZ=4. The structure is built up of one crystallographically independenta 2 tzH cation and one half sulphate ion with crystallographically dictated twofold symmetry.
