Opipramol dipicrate.

ABSTRACT: In the crystal structure of the title compound, C(23)H(31)N(3)O(2+)·2C(6)H(2)N(3)O(7) (-), {systematic name: 1-[3-(5H-dibenz[b,f]azepin-5-yl)prop-yl]-4-(2-hy-droxy-eth-yl)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(2) (1)(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 ?-ring and ?-? stacking inter-actions dominate the crystal packing.
