Orphenadrinium picrate

In the title molecular salt {systematic name: N,N-dimethyl-2-[(2-methyl­phen­yl)(phen­yl)meth­oxy]ethanaminium 2,4,6-tri­nitro­phenolate}, 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 inter­acts 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 inter­molecular C—H⋯O hydrogen bonds, C—H⋯π inter­molecular inter­actions and weak π–π stacking inter­actions [centroid–centroid distances = 3.677 (2) and 3.515 (3) Å} stabilize the crystal packing, creating a three-dimensional network.
