title: [3-(5-Hy-droxy-5H-dibenzo[a,d]cyclo-hepten-5-yl)prop-yl]dimethyl-ammonium 3-carboxyprop-2-enoate.
abstract: 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.
