2-(4-Bromo-benzo-yl)-1-ferrocenyl-spiro-[11H-pyrrolidizine-3,11'-indeno-[1,2-b]quinoxaline].

ABSTRACT: 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?? inter-actions.
