The reaction of dimethyl-amine hydro-chloride, 18-crown-6 and ferric chloride in ethanol yields the title compound, (C(2)H(8)N)[FeCl(4)]·C(12)H(24)O(6), which exhibits an unusual supramolecular structure. The protonated dimethyl-amine contains one NH(2) (+) group, resulting in a 1:1 supra-molecular rotator-stator structure (CH(3)-NH(2) (+)-CH(3))(18-crown-6), through N-H⋯O hydrogen-bonding inter-actions between the ammonium group of the cation and the O atoms of the crown ether. In the crystal, all three components lie on a common crystallographic mirror plane normal to [010].
二甲胺盐酸盐、18-冠-6与氯化铁在乙醇中反应生成标题化合物(C₂H₈N)[FeCl₄]·C₁₂H₂₄O₆，该化合物呈现出一种不寻常的超分子结构。质子化的二甲胺含有一个NH₂⁺基团，通过阳离子铵基团与冠醚的O原子之间的N-H⋯O氢键相互作用，形成了1:1的超分子旋转体-定子结构(CH₃-NH₂⁺-CH₃)(18-冠-6)。在晶体中，所有三种组分位于垂直于[010]的公共晶体学镜面平面上。
