Abstract
Abstract Studies concentrating on hydrogen bonding between the base of 2-aminoheterocyclic compounds 5,7-dimethyl-1,8-naphthyridine-2-amine, 4-phenylthiazol-2-amine, and carboxylic acid derivatives have led to an increased understanding of the role 2-aminoheterocyclic compounds have in binding with carboxylic acid derivatives. Here anhydrous and hydrous multicomponent adducts of 2-aminoheterocyclic compounds such as 5,7-dimethyl-1,8-naphthyridine-2-amine, and 4-phenylthiazol-2-amine have been prepared with 2-chloronicotinic acid, p-hydroxy benzoic acid, maleic acid, and phthalic acid. The five crystalline forms reported are organic salts of which the crystals and complexes were characterized by X-ray diffraction analysis, IR, mp, and elemental analysis. All supramolecular architectures of salts 1 – 5 are stabilized by N H···O hydrogen bonds as well as other non-covalent interactions. These weak interactions combined, all the complexes displayed 3D structure.
