A new polymorph of N-phenyl­phthalimide

During an attempt to prepare a cocrystal of N-phenyl­phthalimide, C(14)H(9)NO(2), with N-(2,3,4,5,6-penta­fluoro­phen­yl)phthalimide, a new ortho­rhom­bic polymorph of the first component was obtained. This new form has Z′ = 0.5 and the mol­ecule is located around a twofold axis, whereas in the prev...

description During an attempt to prepare a cocrystal of N-phenyl­phthalimide, C(14)H(9)NO(2), with N-(2,3,4,5,6-penta­fluoro­phen­yl)phthalimide, a new ortho­rhom­bic polymorph of the first component was obtained. This new form has Z′ = 0.5 and the mol­ecule is located around a twofold axis, whereas in the previously reported polymorph (space group Pbca), the mol­ecule has no crystallographically imposed symmetry. Pairs of C—H⋯O inter­actions between inversion-related phthalimide units arrange mol­ecules into tapes that are further assembled into (010) layers via stacking inter­actions between phthalimide fragments [inter­planar distance = 3.37 (5) Å].
