6-(4-Methylphenyl)-2,10-dioxo-3,9-dioxa-6-aza-1(1,1′) -ferrocenacyclodecaphane

In the title compound, [Fe(C(23)H(23)NO(4))], the two cyclo-penta-dienyl (Cp) rings are nearly parallel, with a dihedral angle of 2.1 (1)°. The distance between the centroids of the Cp rings is 3.277 (8) Å. The relative orientation of the two Cp rings is characterized by a torsion angle of -64.3 (3)° defined by the two centroids and two substituted atoms.
