4-Amino-3-p-Chlorobenzyl-4,5-Dihydro-1,2,4-Triazol-5-One

Abstract

The title compound, C<inf>9</inf>H<inf>9</inf>ClN<inf>4</inf>O, possesses a triazole ring, which is a typically planar six-π-electron partially aromatic system, and displays the characteristic features of a 1,2,4-triazole derivative. In the crystal structure, symmetry-related molecules are linked by intermolecular N - H⋯O and N - H⋯N hydrogen bonds. © 2004 International Union of Crystallography Printed in Great Britain - all rights reserved.
