1-(6-Fluoro-1,3-benzothiazol-2-yl)-2-(1-phenylethylidene)hydrazine

Abstract

The asymmetric unit of the title compound, C15H12FN3S, consists of two independent mol­ecules with comparable geometries. In one mol­ecule, the 1,3-benzothia­zole ring system (r.m.s. deviation = 0.011 Å) forms a dihedral angle of 19.86 (6)° with the phenyl ring. The corresponding r.m.s. deviation and dihedral angle for the other mol­ecule are 0.014 Å and 22.32 (6)°, respectively. In the crystal, mol­ecules are linked via N—H⋯N, C—H⋯F and C—H⋯N hydrogen bonds into a three-dimensional network. The crystal studied was a non-merohedral twin with a refined BASF value of 0.301 (2).
