In the cation of the title salt, C(20)H(24)NO(+)·C(4)H(3)O(4) (-), the N atom in the dimethyl-ammonium group is protonated. The dihedral angle between the mean planes of the two six-membered rings fused to the cyclo-hepten-5-yl ring is 54.4 (1)°. An intra-molecular O-H⋯O hydrogen bond occurs in the anion. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯(O,O) hydrogen bonds and weak C-H⋯O inter-actions, forming a two-dimensional network.
在标题盐C(20)H(24)NO(+)·C(4)H(3)O(4) (-)的阳离子中，二甲基铵基团中的N原子被质子化。与环庚烯-5-基环稠合的两个六元环的平均平面之间的二面角为54.4 (1)°。阴离子中存在分子内O-H⋯O氢键。晶体堆积通过分子间O-H⋯O和N-H⋯(O,O)氢键以及弱的C-H⋯O相互作用得以稳定，形成二维网络。
