Orphenadrinium picrate.

ABSTRACT: In the title molecular salt {systematic name: N,N-dimethyl-2-[(2-methyl-phen-yl)(phen-yl)meth-oxy]ethanaminium 2,4,6-tri-nitro-phenolate}, C(18)H(24)NO(+)·C(6)H(2)N(3)O(7) (-), the phenyl rings of the orphenadrinum cation are disordered [occupancies = 0.662 (4) and 0.338 (4)]. The N atom in the orphenadrinum cation is protonated. The picrate anion inter-acts with the protonated N atom through a bifurcated N-H⋯O hydrogen bond, forming an R(1) (2)(6) ring motif with an adjacent cation. The mean planes of the two o-NO(2) and single p-NO(2) groups in the picrate anion are twisted by 23.0 (6), 31.3 (3) and 6.3 (2)° with respect to the mean planes of the six-membered ring. Weak inter-molecular C-H⋯O hydrogen bonds, C-H⋯π inter-molecular inter-actions and weak π-π stacking inter-actions [centroid
