title: 4-Methyl-2,7-dioxo-3,6-dioxa-1(1,1')-ferrocenacyclo-hepta-phane.
abstract: In the title compound, [Fe(C(15)H(14)O(4))], the two cyclo-penta-dienyl (Cp) rings are nearly parallel, making a dihedral angle of 2.6 (1)°. The distance between the centroids of the Cp rings is 3.309 (8) Å. The relative orientation of the two Cp rings is characterized by a torsion angle of -43.99 (6)° defined by the two centroids and the two substituted C atoms.
