(Received 31 August 2012; accepted 10 October 2012; online 13 October 2012)

In the title compound, C21H26ClN2O4S.Cl, also known as tianeptine hydro­chloride, the seven-membered ring adopts a boat conformation. The dihedral angle between the mean planes of the benzene rings is 44.44 (7)°. There is an intra­molecular hydrogen bond formed via S= O⋯H—N. In the crystal, mol­ecules are connected via pairs of N—H.·O, N—H⋯Cl and O—H⋯Cl hydrogen bonds, forming inversion dimers, which are consolidated by C—H⋯O inter­actions. The dimers are linked by C—H⋯O and C—H⋯Cl inter­actions, forming a two-dimensional network lying parallel to (011).

Comment top

Tianeptine salts are of wide interest since they are crystalline. Although the synthesis of the title compound, tianeptine hydrochloride, has been described (Guzman et al., 2010) we describe in this article an improved method of its synthesis and its crystal structure.

In the title compound (Fig. 1), the seven-membered ring adopts a boat conformation with the values of torsion angles: C1—S1—N1—C13 = -78.4 (2) and C1—C6—C7—C8 = -56.3 (3)°. The dihedral angle between the mean planes of the two benzene rings (C1–C6 and C8–C13) is 44.44 (7)°. There is an intramolecular hydrogen bond in the title molecule which is formed via S1O2···H3B—N2 that stabilizes the molecular structure. In the crystal, the molecules are connected via hydrogen bonds between carboxyl and amine groups and chloride anion, O4—H6···Cl2, N2—H3A···Cl2 and N2—H3B···O3. The crystal structure is further consolidated by intermolecular interactions, C18—H6A···O4, C4—H3···Cl2, C16—H11B···O3 and C7—H7···Cl2 (Table 1 and Fig. 2). The supramolecular structure of tianeptine hydrochloride consists of parallel oriented tricyclic fragment and parallel oriented carbon atom chains (heptanoic acid). Carbon atom chains are linked with hydrogen bonds via chloride anion, amine and carboxylgroup. The torsion angle C8—C7—N2—C15 is -168.4 (2)° so that the carbon atom chain C15—C20 is almost parallel to the benzene ring C8—C13.

The crystal structures of tianeptine polymorphs have been reported recently (Orola et al., 2012). The title structure is more similar with polymorph A structure in which tianeptine molecules are linked via hydrogen bonds between amine and carboxyl groups. The tianeptine molecules in the structure of tianeptine polymorph B are in a zwiterrion form.

Experimental top

Tianeptine sodium salt (0.5 g;1.09 mmol) was dissolved in 20 ml deionized water in a Erlenmeyer flask and added ~3 mmol of hydrochloric acid. Mixture were stirred for 6 h. After 6 h suspension was filtered and washed with cold water. The product was dried and recrystallized from water by slow evaporation at room temperature.

Refinement top

All hydrogen atoms were positioned geometrically with C—H distances ranging from 0.93 to 0.97 Å and refined as riding on their parent atoms with Uiso(H) = 1.5 Ueq(C) for methyl groups and Uiso(H) = 1.2 Ueq(C) for others.

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.
