2-{3-[2-(2-Chlorophenyl)ethyl]-2-oxo-1,2-dihydroquinoxalin-1-yl}acetohydrazide

Abstract

In the title compound, C₁₈H₁₇ClN₄O₂, the dihydroquinoxaline moiety deviates slightly from planarity. The benzene ring and its chloro and methylene substituents are disordered over two sets of sites, with an occupancy ratio of 0.675 (3):0.325 (3). In the crystal, corrugated sheets parallel to (100) are formed by N—H...O, N—H...Cl and N—H...N hydrogen bonds. The structure was refined as a two-component inversion twin.
