5-[5-(4-Chlorophenyl)isoxazol-3-yl]-N-phenyl-1,3,4-oxadiazol-2-amine

Abstract

The title compound, C17H11ClN4O2, consists of chlorophenyl (A), isoxazolyl (B), oxadiazolyl (C) and phenyl (D) rings with twist angles between the planes through neighbouring rings A/B, B/C and C/D of 14.9 (1), 1.8 (1) and 8.9 (1)° respectively. In the crystal, adjacent molecules related by inversion symmetry form columns parallel to the [010] direction through π–π stacking [shortest centroid–centroid separation = 3.6203 (10) Å]; these are cross-linked by N—H...N interactions in the [001] direction.
