Crystal structure of 1-ferrocenyl-2-(4-methylbenzoyl)spiro[11H-pyrrolidizine-3,11′-indeno[1,2-b]quinoxaline]

Abstract

In the title compound, [Fe(C5H5)(C34H28N3O)], the four-fused-rings system of the 11H-indeno[1,2-b]quinoxaline unit is approximately planar [maximum deviation = 0.167 (4) Å] and forms a dihedral angle of 37.25 (6)° with the plane of the benzene ring of the methylbenzoyl group. Both pyrrolidine rings adopt a twist conformation. An intramolecular C—H...O hydrogen bond is observed. In the crystal, molecules are linked by C—H...O hydrogen bonds and weak C—H...π interactions, forming double chains extending parallel to the c axis.
