cations connected by a network of N-H···Cl, C-H···Cl, and π-π supramolecular interactions. The 3 D Hirshfeld surface calculations were performed to investigate the quantitatively relative contribution of these interactions in the crystal packing. The thermal behavior of 1 was characterized by TGA/DTA analysis and Density Functional Theory (DFT); there is a good comparison between the experimental and computed results.
