4-Methyl-2,7-dioxo-3,6-dioxa-1(1,1′)-ferrocenacycloheptaphane
Abstract
In the title compound, [Fe(C15H14O4)], the two cyclopentadienyl (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.
