چکیده انگلیسی
Eight crystalline organic salts derived from 4-phenylthiazol-2-amine and carboxylic acid derivatives (2-chloronicotinic acid, 3-hydroxy-2-naphthoic acid, p-nitrobenzoic acid, 2-hydroxy-5-(phenyldiazenyl)benzoic acid, 5-nitrosalicylic acid, 5-sulfosalicylic acid, oxalic acid, and L-malic acid) were prepared and characterized by X-ray diffraction analysis, IR, mp, and elemental analysis. In all of the salts except 6, 7, and 8, the 4-phenylthiazol-2-amine and carboxylic acid components are held together by two fused heterosynthons: a R22(7) heterosynthon and a R22(8) heterosynthon. All supramolecular architectures of the organic salts 1-8 involve extensive NHâ¯O hydrogen bonds as well as other noncovalent interactions. The role of weak and strong noncovalent interactions in the crystal packing is ascertained. The salts displayed 2D/3D framework structure under these weak interactions.
