Fig. 3. Left: presentation of π-effect (C–H⋯π and π⋯π, Table 3) interactions involved in the N–H⋯Cl (black dashed lines) 2D network of 1; right: a view along b axis of the 3D network formed by linking the N–H⋯Cl 2D layers (three layers are seen in figure) via the C–H⋯Cl and C⋯C interactions. Symmetrically-independent molecules are shown by different colors (dark blue and green for cationic complexes and red, yellow, light blue and pink for chlorine anions).
