Nitrogen rich triaminoguanidine-pyrrole conjugate as supramolecular synthon for the construction of charge-assisted hydrogen bonded network with various carboxylic acids

Abstract In this paper, we report the construction of hydrogen bonded supramolecular assemblies of salt obtained from novel nitrogen rich C3-symmetric star-shaped triamioguanidine-pyrrole conjugate and various carboxylic acids. Different types of supramolecular assembly were achieved by using a variety of carboxylate anions. Formations of all compounds were confirmed by single crystal analysis. The hydrogen bonded 3-D supramolecular network assemblies (1–6) are harvested by utilizing traditional N–H⋯O, O–H⋯O, and weak C–H⋯C interactions. Among all salts, heterosynthons R 2 1 (10) containing traditional N–H⋯O interactions are commonly observed. The thermal stability of salt 1–6 has been examined by thermogravimetric analysis (TGA).
