title: (E)-N-[2-(9-Fluorenyl-idene)-3a,5,7-tri-methyl-3,3a-dihydro-2H-indol-3-yl-idene]-2,4,6-trimethyl-aniline.
abstract: The title compound, C(33)H(30)N(2), has an E configuration at the imine double bond. The angle between the least-squares planes of the imine C=N-C group and the benzene ring of the 2,4,6-trimethylphenyl substituent is 85.38 (11)°. The crystal structure is sustained mainly by inter-molecular π-π inter-actions (3.510 Å) between the two fluorene rings and some C-H⋯π inter-actions.
