(Received 12 September 2012; accepted 15 September 2012; online 29 September 2012)

In the title compound, C16H14ClNO3S, the dihedral angle between the almost-planar benzothia­zole ring system [maximum deviation = 0.012 (3) Å] and the aromatic ring of the trimeth­oxy­phenyl group is 15.56 (6)°. In the crystal, the mol­ecules are arranged into layers parallel to the bc plane, held together only by weak van der Waals forces.

Comment top

Benzothiazole is a well known class of sulfur- and nitrogen-containing heterocyclic aromatic molecules with a broad range of biological activities, such as antimicrobial, antitumoral, antimalarial and antitubercular (Chohan et al., 2003; Hutchinson et al., 2002; Chua et al., 1999; Burger & Sawhney, 1968; Palmer et al., 1971). The title compound is a benzothiazole derivative synthesized as a part of our ongoing project on bioactive hetereocyclic compounds.

The molecular structure of the title compound (Fig. 1) is similar to that reported for the recently published compounds 5-chloro-2-phenyl-1,3-benzothiazole (Yousuf et al., 2012a) and 2-(5-chloro-1,3-benzothiazol-2-yl)-4-methoxyphenol (Yousuf et al., 2012b) with the difference that the phenyl or p-methoxyphenol group is replaced by a trimethoxyphenyl group. The dihedral angle between the almost planar benzothiazole ring system (S1/N1/C1–C7) and the benzene ring of the trimethoxyphenyl group (C8–C13) is 15.56 (6)°. Bond lengths and angles are unexceptional. In the crystal structure the molecules are arranged into layers parallel to the bc plane (Fig. 2) held together only by weak van der Waals forces.

Experimental top

A mixture of 2-amino-4-cholorobenzenethiol (0.159 g, 1 mmol), 3,4,5-trimethoxybenz-aldehyde (0.196 g, 1 mmol), sodium metabisulfite (0.2 g) and N,N-dimethylformamide (10 ml) was refluxed for 2 h in a round-bottomed flask. The completion of reaction was monitored by TLC. After cooling the mixture to room temperature, cold water was added to obtain a white precipitate. Crystallization from ethanol afforded crystals of the title compound (0.298 g, 88.9% yield) found suitable for X-ray diffraction studies.

Refinement top

H atoms were positioned geometrically with C—H = 0.96 or 0.93 Å, and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl H atoms. A rotating group model was applied to methyl 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.
