Abstract: The title compound, C8H3Cl3N2O2, forms crystals in which hydrogen-bonding and Cl...N interactions appear to be equally important to the structure. The molecules form ribbons held together alternately by cyclic (CONH)2 and cyclic (ClCCC[triple bond]N)2 interactions. The ribbons assemble into layers through Cl...Cl interactions. The layers are held together by NH...N[triple bond]C hydrogen bonds, as well as by [pi]-[pi] interactions.

Formula: C8H3Cl3N2O2
