The reaction of propane-1,3-diamine hydrochloride, 18-crown-6 and zinc(II) chloride in methanol solution yields the title complex salt [systematic name: propane-1,3-diaminium tetrachloridozincate(II)-1,4,7,10,13,16-hexaoxacyclooctadecane (1/1)], (C(3)H(12)N(2))[ZnCl(4)] x C(12)H(24)O(6), with an unusual supramolecular structure. The diprotonated propane-1,3-diaminium cation forms an unexpected 1:1 supramolecular rotator-stator complex with the crown ether, viz. C(3)H(12)N(2)(18-crown-6), in which one of the -NH(3)(+) substituents nests in the crown and interacts through N-H...O hydrogen bonding. The other -NH(3)(+) group interacts with the ZnCl(4) anion via N-H...Cl hydrogen bonding, forming cation-crown-anion ribbons parallel to [010].
丙烷 -1,3 -二胺盐酸盐、18 -冠 -6和氯化锌在甲醇溶液中反应生成标题配合物盐[系统名称：丙烷 -1,3 -二铵四氯合锌酸盐(II)-1,4,7,10,13,16 -六氧杂环十八烷(1/1)]，(C₃H₁₂N₂)[ZnCl₄]·C₁₂H₂₄O₆，其具有不寻常的超分子结构。双质子化的丙烷 -1,3 -二铵阳离子与冠醚形成意想不到的1:1超分子旋转体 - 定子配合物，即[C₃H₁₂N₂(18 -冠 -6)]²⁺，其中一个 -NH₃⁺取代基嵌套在冠醚中并通过N - H...O氢键相互作用。另一个 -NH₃⁺基团通过N - H...Cl氢键与[ZnCl₄]²⁻阴离子相互作用，形成平行于[010]的阳离子 - 冠醚 - 阴离子带。
