2,17-Dichloro-8,9,10,11-tetra-hydro-19H-dibenzo[k,n][1,10,4,7]dioxadiaza-cyclo-penta-decine-7,12(6H,13H)-dione.
In the crystal structure of the title compound, C(19)H(18)Cl(2)N(2)O(4), N-H⋯O hydrogen bonds link the mol-ecules 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 inter-actions [Cl⋯centroid = 3.5871 (7) Å]. An intra-molecular N-H⋯O bond occurs.
