Sridharan M, Rajendra Prasad KJ, Zeller M - Acta Crystallogr Sect E Struct Rep Online (2009)

Bottom Line: The overall planarity of the indolo[3,2-c]acridine part of the mol-ecule is inter-rupted by the saturated ethyl-ene group, and the planes of the two halves exhibit a dihedral angle of 22.05 (6)° with each other while themselves being essentially planar.Packing is dominated by C-H⋯π inter-actions.No classical hydrogen bonds or stacking inter-actions are observed.

ABSTRACT
The title compound, C(26)H(19)ClN(2), is a 5,6-dihydro-13H-indolo[3,2-c]acridine prepared by condensation of a 2,3,4,9-tetra-hydro-1H-carbazol-1-one with 2-amino-benzophenone. The crystals undergo a destructive phase change upon cooling at varying temperatures between 270 and 200 K, depending on cooling rate and disturbance by vibration, thus indicating supercooling of the metastable room-temperature structure at lower temperature. The overall planarity of the indolo[3,2-c]acridine part of the mol-ecule is inter-rupted by the saturated ethyl-ene group, and the planes of the two halves exhibit a dihedral angle of 22.05 (6)° with each other while themselves being essentially planar. Packing is dominated by C-H⋯π inter-actions. No classical hydrogen bonds or stacking inter-actions are observed.

Overlay of the title compound with its hydrogenated counterpart (Sridharan et al., 2009b). The chlorobenzene part of the top molecule was used to define the overlay of the two compounds. The other molecules are created by the symmetry operations of their respective structures.
