Succinimidyl 7-(diethylamino)-2-oxo-2H-chromene-3-carboxylate chloroform solvate

In the title molecular structure, C 18 H 18 N 2 O 6 ·CHCl 3 , the dihedral angle between the two fused, essentially planar, six-membered rings is 5.4 (2)°. In the crystal structure, weak intermolecular C—H...O hydrogen bonds and π–π stacking interactions connect molecules into two-dimensional layers.
