Opipramol dipicrate

Abstract

In the crystal structure of the title compound, C23H 31N3O2+·2C6H 2N3O7-, {systematic name: 1-[3-(5H-dibenz[b,f]azepin-5-yl)prop-yl]-4-(2-hydroxy-ethyl)piperazine-1, 4-diium bis(2,4,6-trinitro-phrenolate)} the piperazine group in the opipramol dication is protonated at both N atoms. Each picrate anion inter-acts with the protonated N atom in the cation through a bifurcated N - H⋯O hydrogen bond, forming an R 21(6) ring motif. In the cation, the dihedral angle between the mean planes of the two benzene rings is 50.81 (8) Å. Inter-molecular O - H⋯O and weak C - H⋯O hydrogen bonds, and weak π-ring and π-π stacking inter-actions dominate the crystal packing.
