5-(2-Chlorophenyl)-3-(2H-chromen-3-yl)-1,2,4-oxadiazole

Abstract

In the title compound, C17H11ClN2O2, the central oxadiazole ring carries 2H-chromene and 2-chlorophenyl substituents at the 3- and 5-positions, respectively. C—H...O and C—H...Cl hydrogen bonds form two-dimensional sheets parallel to (212), with each individual molecule involved in six of these weak interactions. The sheets are stacked perpendicular to (212) by offset π–π stacking interactions.
