| Popis: | In this study, a new monoclinic polymorph (space group C2/c) of 2,2′-methylenebis(isoindoline-1,3-dione), C17H10N2O4, is reported and compared to the previously reported triclinic polymorph (space group P\overline{1}). Similarly, both polymorphs consist of a unique molecule in the asymmetric unit (Z′ = 1). The molecular conformations of the two polymorphs are very similar, as shown by the r.m.s. deviation of 0.368 Å (excluding all H atoms). The intermolecular interactions of both polymorphs are described along with the Hirshfeld surface analysis, and the lattice energies are calculated. |
