title: Benzyl 2,5-dioxopyrrolidin-1-yl carbonate.
abstract: The asymmetric unit of the title compound, C(12)H(11)NO(5), contains two independent mol-ecules with similar geometric parameters but different orientations of the phenyl rings. The mol-ecular packing is stabilized by weak nonclassical C-H⋯O hydrogen-bonding inter-actions.
