7-Chloro-3-phenylbenzo[4,5]thiazolo[2,3-c][1,2,4]triazole

Abstract

In the title compound, C14H8ClN3S, the dihedral angle between the approximately planar triple-fused ring system (r.m.s. deviation = 0.065 Å) and the pendant phenyl ring is 62.25 (5)°. In the crystal, molecules are linked into infinite chains along the c-axis direction by C—H...N hydrogen bonds. Aromatic π–π stacking interactions [centroid–centroid distances = 3.7499 (8) and 3.5644 (8) Å] and weak C—H...π interactions are also observed.
