title: 3,4-Diethyl-2,5-dihydro-1H-pyrrole-2,5-dione.
abstract: In the crystal structure of the title compound, C(8)H(11)NO(2), three distinct molecules are present in the asymmetric unit. The molecules are organized in two different hydrogen-bonded tapes, which form a complex layered structure. A structural comparison with the crystal structures of related maleimide derivatives unravels a stepwise evolution of morphological complexity with increasing molecular complexity for this class of compounds.
