1-Acetyl-4-(p-Chloro­benzyl­idene­amino)-3-Methyl-4,5-Di­hydro-1H-1,2,4-Triazol-5-One

Abstract

The molecules of the title compound, C<inf>12</inf>H<inf>11</inf>ClN <inf>4</inf>O<inf>2</inf>, 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.
