Abstract
Interaction of 2-aminothiazole (AT) base with 3,5-dinitrobenzoic acid (DNB) and 3,5-dinitrosalicylic acid (DNS) gave 1 : 1 molecular species. The salts were investigated using IR, NMR and UV-Vis spectroscopic techniques. Proton transfer occurred from the acid to the hetero nitrogen atom of the aminothiazole to form a Lewis salt. The crystal structure of AT-DNB (1) and AT-DNS (2) were determined by single crystal X-ray diffraction. Both two compounds crystallize in a monoclinic cell, (space group P2 1 /c ). The structures were determined by direct methods and refined to R = 0.055 for 1 and R = 0.074 for 2.
