Three isomeric N-(nitrophenyl)-succinimides: isolated molecules, hydrogen-bonded sheets and a hydrogen-bonded three-dimensional framework

Molecules of N-(2-nitrophenyl) succinimide, C10H8N2O4, are linked into sheets by a combination of C-H center dot center dot center dot O and C-H center dot center dot center dot pi(arene) hydrogen bonds. Molecules of N-(3-nitrophenyl) succinimide are linked into a three-dimensional framework by a combination of a two-centre C-H center dot center dot center dot O hydrogen bond and a three-centre C-H center dot center dot center dot(O)(2) hydrogen bond. Molecules of N-(4-nitrophenyl) succinimide which lie across twofold rotation axes in space group C2/c, participate in no direction-specific intermolecular interactions.
