چکیده
In the title compound, [Fe(C5H5)(C33H25BrN3O)], the fused four-ring system, 11H-indeno-[1,2-b]quinoxaline is essentially planar, with a maximum deviation of 0.087 (3) Å from the least-squares plane of the attached benzene ring. The pyrrolidine rings adopt envelope conformation and make a dihedral angle of 51.76 (19)° with each other. The cyclopentadiene rings of the ferrocenyl moiety have an eclipsed conformation. The Br atom deviates by 0.0190 (9) Å from the attached benzene ring. The mol-ecular structure features an intra-molecular C-H⋯N inter-action, which generates an S(8) ring motif. The crystal packing features C-H⋯O inter-actions, which generate R 2 (2)(18) centrosymmetric dimers, as well as C-H⋯π inter-actions.
