Abstract

During an attempt to prepare a cocrystal of N-phenyl-phthalimide, C(14)H(9)NO(2), with N-(2,3,4,5,6-penta-fluoro-phen-yl)phthalimide, a new ortho-rhom-bic polymorph of the first component was obtained. This new form has Z' = 0.5 and the mol-ecule is located around a twofold axis, whereas in the previously reported polymorph (space group Pbca), the mol-ecule has no crystallographically imposed symmetry. Pairs of C-H⋯O inter-actions between inversion-related phthalimide units arrange mol-ecules into tapes that are further assembled into (010) layers via stacking inter-actions between phthalimide fragments [inter-planar distance = 3.37 (5) Å].
