2,17-Dichloro-8,9,10,11-tetrahydro-19H-dibenzo[k,n][1,10,4,7]dioxadiazacyclopentadecine-7,12(6H,13H)-dione

Abstract

In the crystal structure of the title compound, C19H18Cl2N2O4, N—H...O hydrogen bonds link the molecules into infinite chains along the b axis. The structure also features weak C—H...O and C—H...Cl hydrogen bonds and C—H...π and (lone pair)...π interactions [Cl...centroid = 3.5871 (7) Å]. An intramolecular N—H...O bond occurs.
