title: 1,2-Di-2-furylethane-1,2-dione.
abstract: 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.
