Seven inorganic salts of 3, 5-diamino-1, 2, 4-triazole (dat) with inorganic acids were prepared within our project focused on the crystal engineering of novel NLO materials and their X-ray structures were determined. Three triclinic compounds, dat (1+) selenate dihydrate, dat (1+) sulphate dihydrate and dat (1+) perchlorate, crystallize in the space group P. Three monoclinic structures of dat (1+)–ie nitrate, chloride hemihydrate and ...
