title: Crystal structure of 2-(1H-imidazol-4-yl)ethanaminium chloride.
abstract: The title mol-ecular salt, C5H10N3 (+)·Cl(-), was obtained as by-product in the attempted synthesis of a histamine derivative. The terminal amino group of the starting material is protonated. The Cimidazole-C-C-N(H3)(+) group in the cation is in an anti conformation with a torsion angle of 176.22 (10)°. In the crystal, cations and anions are linked via N-H⋯N and N-H-Cl hydrogen bonds, forming a two-dimensional network parallel to (10-1). A single weak C-H⋯Cl hydrogen bond completes a three-dimensional network.
