Abstract
The title compound, [Fe(C(5)H(5))(C(21)H(21)O(3))], was obtained from successive Stobbe condensations between ketones and dimethyl succinate. The succinic anhydride five-membered ring is distorted significantly from planarity, with the butadiene moiety being twisted by 49.3 (2) degrees from planarity and the C atoms at the succinic anhydride end of the alkene bonds showing significant pyramidalization. The cyclopentadiene rings of the ferrocenyl moiety adopt an almost eclipsed conformation.
