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.
标题分子盐C₅H₁₀N₃⁺·Cl⁻是在尝试合成组胺衍生物时作为副产物得到的。起始原料的末端氨基被质子化。阳离子中的C咪唑-C-C-N(H₃)⁺基团处于反式构象，扭转角为176.22 (10)°。在晶体中，阳离子和阴离子通过N-H⋯N和N-H-Cl氢键相连，形成平行于(10-1)的二维网络。一个单一的弱C-H⋯Cl氢键完善了三维网络。
