1,2-Di-2-furylethane-1,2-dione
The title compound, C(10)H(6)O(4), lies across a twofold rotation axis through the midpoint of the C-C bond between the two carbonyl groups. The furan ring plane and the plane through all atoms are inclined at 23.88 (1)°. In the crystal structure, weak C-H⋯O hydrogen bonds form sheets in the bc plane and columns down the c axis.

In the title compound, C(24)H(15)NO(3), the fused naphthaquin-one-pyrrole unit is approximately planar, the naphthaquinone ring system making a dihedral angle of 2.91 (10)° with the pyrrole ring. The plane of the pyrrole ring makes a dihedral angle 61.64 (14)° with that of the benzene ring of the benzoyl-methyl-ene group. The crystal structure is stablized by intra-molecular C-H⋯O inter-actions.
