Abstract

Imidazole base was crystallized with different aromatic carboxylic acids 24dihydroxybenzoic acid 5chlorosalicylic acid and 18naphthalic acid affording three new binary molecular organic salts of C3H5N2+·C7H5O4 − 1 C3H5N2 +·C7H4O3Cl−−C7H5O3Cl 2 and C3H5N2 +−C12H7O4 − 3 Proton transfer occurs from the COOH of carboxylic acid to nitrogen of imidazole in all complexes 1–3 leading to the hydrogen bond NH…O in all structures To our knowledge the recognition pattern between the carboxylic acid group and imidazole acidimidazole synthon is less wellstudied so far The cooperation among COOH COO− and imidazolium cation functional groups for the observed hydrogen bond synthons is examined in the three structures Generally the strong NH…O and OH…O hydrogen bonds define supramolecular architecture and connectivity within chains while weaker CH…O hydrogen bonds play the dominant role in controlling the interactions between layers in these novel organic salts Thermal stability of these compounds has been investigated by thermogravimetric analysis TGA of mass loss
