The title compound {systematic name: 3-chloro-5-[3-(dimethylamino)propyl]-10,11-dihydro-5H-dibenz[b,f]azepinium picrate}, C19H24ClN2+·C6H2N3O7−, crystallizes with two independent cation–anion pairs in the 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)° with a 3-(dimethylamino)propyl group extending away from the apex of this ring. In the picrate anion, the mean planes of the two o-NO2 groups in each anion are twisted by 3.7 (2)/31.9 (3) and 31.3 (1)/11.4 (0)°, 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 p-NO2 groups are twisted by 6.6 (1) and 2.88°, respectively, from the mean plane of the benzene ring. The crystal packing features bifurcated N—H⋯(O,O) intermolecular hydrogen-bond interaction, which connects each cation–anion pair. Additional π–π ring and C—H⋯π weak intermolecular interactions are also observed.

Clorimipramine hydrochloride (3.5 g, 0.01 mol) in 25 ml of a mixture of (1:1) acetonitrile & methanol and picric acid (4.5 g, 0.01 mol) in 25 ml of mixture of (1:1) acetonitrile & methanol were mixed and stirred in a beaker at 318 K for two hours. The mixture was kept aside for about five days at room temperature. The separated salt was filtered and dried in vacuum desiccator over phosphorous pentoxide. The crystals obtained (m.p: 393 - 395 K) were used for x-ray studies.
All of the H atoms were placed in their calculated positions and then refined using the riding model with N—H = 0.93 Å, C—H = 0.95–0.99 Å, and with Uiso(H) = 1.18–1.51Ueq(C,N).
Chlorimipramine [IUPAC name: 3-chloro-5-(3-dimethylaminopropyl)-10, 11-dihydro-5H-dibenz[b,f]azepine] is a tricyclic antidepressant that was developed in the 1960's by the Swiss drug manufacturer Geigy (now known as Novartis) and has been in clinical use worldwide for decades. Chlorimipramine, a 3-chloro derivative of imipramine, is a strong, but not completely selective, serotonin reuptake inhibitor (SSRI), which like the primary active metabolite desmethylclomipramine acts preferably as a norepinephrine reuptake inhibitor. It is used in the treatment of obsessive-compulsive disorder (Albert et al., 2002) and panic disorder (Cassano et al., 1988). The effect of chlorimipramine and maprotiline on experimental anxiety in humans has been reported (Guimaraes et al., 1987). The use of chlorimipramine in humans as an effective, non-toxic cancer-therapeutic having a strong selectivity between cancer cells and normal cells on the basis of their mitochondrial function has also been discussed (Daley et al., 2005).
The crystal and molecular structure of tricyclic antidepressant imipramine hydrochloride (Post et al., 1975), chloripramine hydrochloride (Post & Horn, 1977; Hallberg et al., 1984), amitriptylinium picrate (Bindya et al., 2007), mepazinium picrate (Yathirajan et al., 2007), imipraminium picrate (Harrison, Bindya et al., 2007), nevirapinium picrate (Harrison, Sreevidya et al., 2007) and desipraminium picrate (Swamy et al., 2007) have been reported. In view of the importance of chlorimipramine and to study the hydrogen bonding patterns in the title compound, (I), C25H26ClN5O7, a
is reported.The title compound,C25H26ClN5O7, crystallizes with two independent cation-anion pairs [C19H24ClN2+. C6H2N3O7-] in the π–π ring intermolecular interactions (Table 2, Fig. 3) and a weak C12A—H12A···Cg7 π-ring intermoleclar interaction (H12A···Cg7 = 2.83°, C12a—H12A···Cg7 = 145°, C12A···Cg7 = 3.656 (4)°; x, -1 + y, z).
(Fig. 1). The chlorimipraminium cation contains two benzene rings (one halogenated) fused to a V-shaped, seven-membered azepine ring whose mean planes are separated by 61.1 (0)° (A) and 66.5 (8)° (B) with a 3-dimethylaminopropyl) group extending away from the apex of the bent azepine group (Torsion angles C1A—N1A—C15A—C16A = 59.19 (14)°; C1B—N1B—C15B—C16B = 165.18 (10)°). In the picrate anion, the mean planes of the two o-NO2 groups (O21D—N2D—O22D & O61D—N6D—O62D; O21C—N2C—O22C & O61C—N6C—O62C are twisted by 3.7 (2)°, 31.9 (3)° and 31.3 (1)°, 11.4 (0)°, respectively, with respect to the mean plane of the 6-membered benzene ring (Fig. 1). The phenolate oxygen atoms are bent slightly away from the mean plane of the benzene ring (Torsion angles O1D—C1D—C2D—C3D = 171.41 (12)°; O1C—C1C—C2C—C3C = -172.94 (12)°). The mean planes of the p-NO2 oxygen atoms (O41D—N4D—O42D & O41C—N4C—O42C) are twisted by 6.6 (1)° and 2.88°, respectively, from the mean plane of the benzene ring. The difference in the twist angles of the mean planes of the two o-NO2 groups and the bend in the phenolate oxygen atoms in each of the cation units can be attributed to the influence of strong bifurcated (3-center) "side" hydrogen bond intermolecular interactions with the nitrogen atom in the 3-dimethylaminopropyl group of their cation neighbors (N2A—H2AB···O1D, N2A—H2AB···O2D and N2B—H2BB···O1C, N2B—H2BB···O62C; Fig. 2, Table 1). Crystal packing is also influenced by additional weakA density functional theory (DFT) geometry optimization
calculation (Schmidt & Polik, 2007) was performed on the two independent cation-anion pairs (C19H24ClN2+. C6H2N3O7-) of the with the GAUSSIAN03 program package (Frisch et al., 2004; Becke, 1988; Lee et al., 1988) and the 3–21 G basis set. Starting geometries were taken from X-ray data. In the cation, the angle between the two benzene rings fused to the azepine ring decreases to 53.2 (9)° (A) and 55.8 (5)°, a change of -7.8 (1)° and -10.7 (3)°, respectively. In the picrate anion, the mean planes of the two o-NO2 groups (O21D—N2D—O22D & O61D—N6D—O62D; O21C—N2C—O22C & O61C—N6C—O62C become twisted by 18.2 (8)°, 6.3 (5)° and 15.5 (6)°, 13.6 (4)°, with respect to the mean plane of the 6-membered benzene ring, changes of +14.5 (6)°, -25.5 (8)° and -15.7 (5)°, +2.2 (4)°, respectively. The torsion angles of the phenolate oxygen atoms (O1D—C1D—C2D—C3D & O1C—C1C—C2C—C3C) become 175.1 (6)° and -171.6 (7)°, changes of +3.7 (5)° and -1.2 (7)° relative to the mean plane of the benzene ring. The mean planes of the p-NO2 oxygen atoms (O41D—N4D—O42D & O41C—N4C—O42C) become twisted by 0.4 (8)° and 6.2 (3)°, changes of -6.3 (1)° and +3.3 (5)°, respectively, from the mean plane of the anion benzene ring. The dihedral angle between the benzene ring of the anion and the benzene and chloro substituted benzene ring in the cation change from 70.1 (5)°, 15.0 (4)° and 67.9 (3)°, 4.3 (5)° to 35.1 (5)°, 44.8 (3)° and 36.7 (3)°, 12.0 (2)°, changes of -35.0 (0)°, +21.6 (9)°, and -23.1 (0)°, +7.6 (7)°, respectively. Examination of the partial charges from the DFT geometry optimization indicate that H2BD (0.43570) is slightly more positive than H2AB (0.424847) producing a slightly stronger associated with the N2B atom of the cation-anion pair (B & C groups).For related structures, see: Bindya et al.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Chlorimipramine [IUPAC name: 3-chloro-5-(3-dimethylaminopropyl)-10, 11-dihydro-5H-dibenz[b,f]azepine] is a tricyclic antidepressant that was developed in the 1960's by the Swiss drug manufacturer Geigy (now known as Novartis) and has been in clinical use worldwide for decades. Chlorimipramine, a 3-chloro derivative of imipramine, is a strong, but not completely selective, serotonin reuptake inhibitor (SSRI), which like the primary active metabolite desmethylclomipramine acts preferably as a norepinephrine reuptake inhibitor. It is used in the treatment of obsessive-compulsive disorder (Albert et al., 2002) and panic disorder (Cassano et al., 1988). The effect of chlorimipramine and maprotiline on experimental anxiety in humans has been reported (Guimaraes et al., 1987). The use of chlorimipramine in humans as an effective, non-toxic cancer-therapeutic having a strong selectivity between cancer cells and normal cells on the basis of their mitochondrial function has also been discussed (Daley et al., 2005).
The crystal and molecular structure of tricyclic antidepressant imipramine hydrochloride (Post et al., 1975), chloripramine hydrochloride (Post & Horn, 1977; Hallberg et al., 1984), amitriptylinium picrate (Bindya et al., 2007), mepazinium picrate (Yathirajan et al., 2007), imipraminium picrate (Harrison, Bindya et al., 2007), nevirapinium picrate (Harrison, Sreevidya et al., 2007) and desipraminium picrate (Swamy et al., 2007) have been reported. In view of the importance of chlorimipramine and to study the hydrogen bonding patterns in the title compound, (I), C25H26ClN5O7, a crystal structure is reported.
The title compound,C25H26ClN5O7, crystallizes with two independent cation-anion pairs [C19H24ClN2+. C6H2N3O7-] in the asymmetric unit (Fig. 1). The chlorimipraminium cation contains two benzene rings (one halogenated) fused to a V-shaped, seven-membered azepine ring whose mean planes are separated by 61.1 (0)° (A) and 66.5 (8)° (B) with a 3-dimethylaminopropyl) group extending away from the apex of the bent azepine group (Torsion angles C1A—N1A—C15A—C16A = 59.19 (14)°; C1B—N1B—C15B—C16B = 165.18 (10)°). In the picrate anion, the mean planes of the two o-NO2 groups (O21D—N2D—O22D & O61D—N6D—O62D; O21C—N2C—O22C & O61C—N6C—O62C are twisted by 3.7 (2)°, 31.9 (3)° and 31.3 (1)°, 11.4 (0)°, respectively, with respect to the mean plane of the 6-membered benzene ring (Fig. 1). The phenolate oxygen atoms are bent slightly away from the mean plane of the benzene ring (Torsion angles O1D—C1D—C2D—C3D = 171.41 (12)°; O1C—C1C—C2C—C3C = -172.94 (12)°). The mean planes of the p-NO2 oxygen atoms (O41D—N4D—O42D & O41C—N4C—O42C) are twisted by 6.6 (1)° and 2.88°, respectively, from the mean plane of the benzene ring. The difference in the twist angles of the mean planes of the two o-NO2 groups and the bend in the phenolate oxygen atoms in each of the cation units can be attributed to the influence of strong bifurcated (3-center) "side" hydrogen bond intermolecular interactions with the nitrogen atom in the 3-dimethylaminopropyl group of their cation neighbors (N2A—H2AB···O1D, N2A—H2AB···O2D and N2B—H2BB···O1C, N2B—H2BB···O62C; Fig. 2, Table 1). Crystal packing is also influenced by additional weak π–π ring intermolecular interactions (Table 2, Fig. 3) and a weak C12A—H12A···Cg7 π-ring intermoleclar interaction (H12A···Cg7 = 2.83°, C12a—H12A···Cg7 = 145°, C12A···Cg7 = 3.656 (4)°; x, -1 + y, z).
A density functional theory (DFT) geometry optimization molecular orbital calculation (Schmidt & Polik, 2007) was performed on the two independent cation-anion pairs (C19H24ClN2+. C6H2N3O7-) of the asymmetric unit with the GAUSSIAN03 program package (Frisch et al., 2004; Becke, 1988; Lee et al., 1988) and the 3–21 G basis set. Starting geometries were taken from X-ray refinement data. In the cation, the angle between the two benzene rings fused to the azepine ring decreases to 53.2 (9)° (A) and 55.8 (5)°, a change of -7.8 (1)° and -10.7 (3)°, respectively. In the picrate anion, the mean planes of the two o-NO2 groups (O21D—N2D—O22D & O61D—N6D—O62D; O21C—N2C—O22C & O61C—N6C—O62C become twisted by 18.2 (8)°, 6.3 (5)° and 15.5 (6)°, 13.6 (4)°, with respect to the mean plane of the 6-membered benzene ring, changes of +14.5 (6)°, -25.5 (8)° and -15.7 (5)°, +2.2 (4)°, respectively. The torsion angles of the phenolate oxygen atoms (O1D—C1D—C2D—C3D & O1C—C1C—C2C—C3C) become 175.1 (6)° and -171.6 (7)°, changes of +3.7 (5)° and -1.2 (7)° relative to the mean plane of the benzene ring. The mean planes of the p-NO2 oxygen atoms (O41D—N4D—O42D & O41C—N4C—O42C) become twisted by 0.4 (8)° and 6.2 (3)°, changes of -6.3 (1)° and +3.3 (5)°, respectively, from the mean plane of the anion benzene ring. The dihedral angle between the benzene ring of the anion and the benzene and chloro substituted benzene ring in the cation change from 70.1 (5)°, 15.0 (4)° and 67.9 (3)°, 4.3 (5)° to 35.1 (5)°, 44.8 (3)° and 36.7 (3)°, 12.0 (2)°, changes of -35.0 (0)°, +21.6 (9)°, and -23.1 (0)°, +7.6 (7)°, respectively. Examination of the partial charges from the DFT geometry optimization indicate that H2BD (0.43570) is slightly more positive than H2AB (0.424847) producing a slightly stronger proton charge associated with the N2B atom of the cation-anion pair (B & C groups).
