The title compound systematic name: 3-chloro-5-3-(dimethyl{\-}amino)prop{\-}yl-10,11-dihydro-5{\it H}-dibenz{\it b},{\it f}azepinium picrate, C\sb 19H\sb 24ClN\sb 2\sp +⋅C\sb 6H\sb 2N\sb 3O\sb 7\sp -}}, crystallizes with two independent cation—anion pairs in the asymmetric unit. The chlorimipraminium cation contains two benzene rings (one with a chloro substituent) fused to a V-shaped seven-membered azepine ring whose mean planes are separated by 61.1(0) and 66.5(8)\circ with a 3-(dimethyl\-amino)propyl group extending away from the apex of this ring. In the picrate anion, the mean planes of the two \it o-NO\sb 2 groups in each anion are twisted by 3.7(2)/31.9(3) and 31.3(1)/11.4(0)\circ, respectively, with respect to the mean plane of the six-membered benzene ring. The phenolate O atoms are bent slightly away from the mean plane of the benzene ring. The mean planes of the \it p-NO\sb 2 groups are twisted by 6.6(1) and 2.88\circ, respectively, from the mean plane of the benzene ring. The crystal packing features bifurcated N—-H⋅s(O,O) inter\-molecular hydrogen-bond inter\-action, which connects each cation—anion pair. Additional π—π ring and C—-H⋅sπ weak inter\-molecular inter\-actions are also observed.
