Four Non-covalent Bonded Anhydrous Supramolecular Salts of Triphenylmethylamine and Organic Acids

Abstract

This text reports the triphenylmethylamine based supramolecular salts formation in crystalline solids 1–4, where the acids have been integrated. Addition of the triphenylmethylamine to the solution of organic acid makes the corresponding supramolecular assemblies. All crystallize as their anhydrous organic salts and they have been featured via IR, mp, EA and XRD in detail. The major driving force in 1–4 is the classical H-bonds between triphenylmethylamine and the acids. The other extensive non-covalent associations also play great functions in space extension with the molecular partners in the relevant crystals. The hetero supramolecular synthons were built at these salts and the characteristic R44(12) rings have been enclosed under the H-bonds associations at 1–2. For the interplay of the classical H-bonds and various non-covalent bonds, all the salts adopted the 3D net.
