In the title salt, (C5H6N)[ZnCl3(C5H5N)], the Zn2+ atom is four-coordinated by one pyridine N atom and three chloride ligands, forming a slightly distorted tetra-hedral ZnNCl3 environment. In the crystal, the cation and anion are linked by bifurcated N-H⋯(Cl,Cl) and C-H⋯Cl hy-dro-gen bonds, generating a supra-molecular assembly that is further consolidated by π-π stacking inter-actions between aromatic rings. Hirshfeld surface analysis shows that H⋯Cl/Cl⋯H contacts are the dominant contribution to the crystal packing, accounting for 44.1% of the total surface contacts, followed by H⋯H (29.9%) and H⋯C/C⋯H (15.0%) inter-actions.
