(Received 2 April 2013; accepted 5 April 2013; online 13 April 2013)

The title compound, C16H12NOSSe+·HSO4, was obtained from a mixture of 3-(4-meth­oxy­phen­yl)[1,3]selenazolo[2,3-b][1,3]benzo­thia­zol-4-ium chloride and potassium hydrogen sulfate. In the cation, the benzene ring is twisted by 71.62 (7)° from the tricycle mean plane. In the crystal, O—H⋯O hydrogen bonds link the anions into chains along [100]. The anions in adjacent chains are linked via weak C—H⋯O hydrogen bonds. The crystal packing exhibits short inter­molecular contacts between the chalcogen unit and the O atoms: Se⋯O(anion) 2.713 (3), Se⋯O(cation) 2.987 (3) and S⋯O(anion) 2.958 (3) Å.

Comment top

In the last years, the selenium- and nitrogen-containing heterocycles have attracted considerable attention owing to the variety of their pharmacological properties (Back, 2009; Mlochowski & Giurg, 2009; Mukherjee et al., 2010; Selvakumar et al., 2010). This article describes the structure of 3-(4-methoxyphenyl)[1,3]selenazolo[2,3-b][1,3]benzothiazol-4-ium hydrogen sulfate, [C16H12NOSSe]+.[HSO4]-, (I), which was obtained by the reaction of 3-(4-methoxyphenyl)[1,3]selenazolo[2,3-b][1,3]benzothiazol-4-ium chloride (Borisov et al., 2012) with potassium hydrogen sulfate (Figure 1).

The compound I is a salt consisting of 3-(4-methoxyphenyl)[1,3]selenazolo[2,3-b][1,3]benzothiazol-4-ium cation and hydrogen sulfate anion (Figure 2). The cation of I comprises a fused tricyclic system containing two five-membered rings (1,3-selenazole and 1,3-thiazole) and one six-membered ring (benzene). The tricyclic system is practically planar (r.m.s deviation = 0.020 Å). The methoxy group is almost coplanar to the plane of the phenyl substituent (the C12—C13—O1—C16 torsion angle is 1.7 (5)°). The dihedral angle between the mean planes of the tricyclic system and methoxyphenyl fragment is 71.82 (6)°.

In the crystal, anions form chains along the a axis through the intermolecular O—H···O hydrogen bonding interactions (Table 1, Figure 3). Weak intermolecular C—H···O hydrogen bonds (Table 1, Figure 3) as well as non-valent attractive Se···O (Se1···O3b 2.713 (3), Se1···O1c 2.987 (3), Se1···O3 3.366 (3), Se1···O5b 3.423 (3) Å) and S···O [S9···O2a 2.958 (3) and S9···O1c 3.050 (3) Å] interactions consolidate further the three-dimensional-crystal packing (Figure 3) [symmetry codes: (a) x, y, z + 1; (b) x–1, y, z; (c) –x, y + 0.5, –z + 1].

Experimental top

A mixture of 3-(4-methoxyphenyl)[1,3]selenazolo[2,3-b][1,3]benzothiazol-4-ium chloride (0.19 g, 0.5 mmol) with KHSO4 (0.072 g, 0.53 mmol) in CH3OH (20 ml) was refluxed for 0.5 h to dissolve the starting materials. After that the reaction mixture was concentrated in vacuo. Then CH2Cl2 (20 ml) was added to the solid to give precipitate of KCl, which was separated by filtration. The filtrate was concentrated in vacuo. The solid was re-crystallized from CH2Cl2 to give I as colorless crystals. Yield is 93%. M.p. = 510–512 K. 1H NMR (DMSO-d6, 600 MHz, 302 K): δ = 8.42 (1H, d, J = 8.0, H8), 8.23 (1H, s, H2), 7.63 (1H, t, J = 8.0, H7), 7.59 (2H, d, J = 8.8, H11, H15), 7.48 (1H, t, J = 8.0, H6), 7.25 (2H, d, J = 8.8, H12, H14), 6.81 (1H, d, J = 8.1, H5), 3.87 (3H, s, OMe).

Refinement top

The hydroxyl hydrogen atom was localized in the difference-Fourier map and included in the refinement with fixed positional and isotropic displacement parameters [Uiso(H) = 1.5Ueq(O)]. The other hydrogen atoms were placed in calculated positions with C—H = 0.95 Å (CH) and 0.98 Å (CH3) and refined in the riding model with fixed isotropic displacement parameters [Uiso(H) = 1.5Ueq(C) for the CH3 group and 1.2Ueq(C) for the CH groups].

Special details top

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.
