Crystal structure and Hirshfeld surface analysis of 4-aminopyridinium thiocyanate–4-aminopyridine (1/1)

In the crystals of the title compound, C5H7N2+·CNS-·C5H6N2, the components are linked by three N-H⋯N and two N-H⋯S hydrogen bonds, resulting in two inter-penetrating three-dimensional networks. Hirshfeld surface analysis shows that the most important contributions to the crystal packing are from H⋯H (36.6%), C⋯H/H⋯C (20.4%), S⋯H/H⋯S (19.7%) and N⋯H/H⋯N (13.4%) inter-actions.
