1-Acetyl-4-(p-chlorobenzylideneamino)-3-methyl-4,5-dihydro-1 H-1,2,4-triazol-5-one

Abstract

The molecules of the title compound, C12H11ClN 4O2, are arranged as layers, stacking approximately along the b axis through C - H⋯O intermolecular hydrogen bonds. Some of these hydrogen-bond interactions which link two centrosymetrically related molecules generate π-;π-stacking interactions between triazole rings. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.
