Crystal structure and Hirshfeld surface analysis of (E)-N-(4-propyl­oxybenzyl­idene)benzo[d]thia­zol-2-amine

The title compound, C(17)H(16)N(2)OS, was synthesized by a condensation reaction between 2-amino benzo­thia­zole and 4-N-propoxybenzaldehyde. The benzo[d]thia­zole ring system is nearly planar (r.m.s. deviation 0.0088 Å) and makes a dihedral angle of 3.804 (12)° with the phenyl ring. The configuration about the C=N double bond is E. In the crystal structure, pairs of C—H⋯N hydrogen bonds and C—H⋯π inter­actions link the mol­ecules into inversion dimers with an R (2) (2)(16) ring motif. These dimers are additionally linked by weak π–π stacking inter­actions between the phenyl rings, leading to a layered arrangement parallel to (010). Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the packing arrangement are from H⋯H (47.9%) and C⋯H/H⋯C (25.6%) inter­actions.
