{2-[(1,3-Benzothiazol-2-yl)methoxy]-5-fluorophenyl}(4-chlorophenyl) methanone

Abstract

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 π-π interactions [centroid-centroid distance = 3.877 (3) Å] lead to a criss-cross molecular packing along the c axis.
