1,1'-diacetyl-3-hydroxy-2,2',3,3'-tetrahydro-3,3'-bi(1H-indole)-2,2'-dione.
In the title compound, C20H16N2O5, both of the 1-acetylisatin (1-acetyl-1H-indole-2,3-dione) moieties are planar and form a dihedral angle of 74.1 (1) degrees. Weak intermolecular hydrogen bonds and C-H...pi interactions stabilize the packing in the crystal.
