A three-dimensional hydrogen-bonded framework in N-(3-nitrophenyl)phthalimide, and hydrogen-bonded chains of rings in N-(3,5-dinitrophenyl)phthalimide, linked into sheets by dipolar interactions.

Abstract

Molecules of N-(3-nitrophenyl)phthalimide, C(14)H(8)N(2)O(4), are linked into a three-dimensional framework by four distinct C-H...O hydrogen bonds [H...O = 2.35-2.58 A, C.O = 3.105 (5)-3.432 (5) A and C-H...O = 128-167 degrees ]. Molecules of N-(3,5-dinitrophenyl)phthalimide, C(14)H(7)N(3)O(6), lie across twofold rotation axes in space group P2/n and are linked by a single C-H...O hydrogen bond [H...O = 2.58 A, C...O = 3.410 (2) A and C-H..O = 147 degrees ] into chains of rings. These chains are weakly linked into sheets by intermolecular interactions involving short dipolar O...N and O...C contacts.
