The asymmetric unit of the title compound, C21H13ClFNO2S, contains two independent mol­ecules with similar conformations. In the mol­ecules, the thia­zole ring is essentially planar [maximum atomic deviations = 0.014 (4) and 0.023 (5) Å] and is oriented with respect to the fluoro­phenyl ring and chloro­phenyl rings at 9.96 (18) and 70.39 (18)° in one mol­ecule and at 7.50 (18) and 68.43 (18)° in the other; the dihedral angles between the fluoro­phenyl and chloro­phenyl rings are 64.9 (2) and 64.6 (2)°, respectively. Inter­molecular C—H⋯O and C—H⋯F hydrogen bonds stabilize the three-dimensional supra­molecular architecture. Weak C—H⋯π and ππ inter­actions [centroid–centroid distance = 3.877 (3) Å] lead to a criss-cross mol­ecular packing along the c axis.

Comment top

Substituted benzothiazole derivatives exhibit various pharmacological properties such as analgesic, antimicrobial, antidepressant, antitumor, antihypertensive, anthelmintic, and herbicidal activity (Kelarev et al., 2003). Thus the biological features of new benzothiazole derivatives is of great scientific interest (Telvekar et al., 2012; Saeed et al., 2010; Rana et al., 2007). Several crystal structures of the benzothiazoles have been reported (Nayak et al., 2013; Venugopala et al., 2012). Here, we report the single-crystal structure of the title compound.

The title compound, C21H13ClFNO2S, prefers two symmetry independent molecules in the asymmetric unit (Fig. 1). The conformation of the individual molecules adopt the dihedral angles of 64.8 (2)° and 66.6 (2)° between the planes of their respective benzothiazole and chlorophenylmethanone groups. Intermolecular C—H···O and C—H···F hydrogen bond chains stabilize the three dimension molecular assembly. Further, the C—H···π [2.83 Å, Cg1 = Centroid of five membered ring S1/C1/C6/N1/C7; 2.82 Å, Cg2 = Centroid of five membered ring S2/C22/C27/N2/C28] and π···π [Cg3···Cg4 = 3.877 (3) Å, Cg3 = Centroid of six membered ring C16—C21 and Cg4 = Centroid of six membered ring C30—C35] interactions lead to criss-cross molecular packing along the c axis.

Experimental top

To a solution of (2-chloromethyl)benzo[d]thiazole (1 mmol) and (4-chlorophenyl)(5-fluoro-2-hydroxyphenyl)methanone (1 mmol) in dry THF, dry potassium carbonate (1 mmol) was added and stirred at room temperature. The reaction mixture was added and the reaction mixture was stirred at room temperature for 14 h. The reaction mixture was concentrated to remove the solvent, diluted with ethyl acetate, washed with water, brine solution and dried over anhydrous sodium sulfate. The organic layer was concentrated to yield a residue which was purified by column chromatography using ethyl acetate and n-hexane as eluent (7:3, Rf = 0.70) to afford the product in 78% as a white solid (m. p. 419 (2) K). Suitable crystals for single-crystal X-ray study were obtained from acetone solvent using slow evaporation technique at room temperature.

Refinement top

All H atoms were positioned geometrically and refined using a riding model with Uiso(H)= 1.2 Ueq(C).

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
