(RS)-Tricarbon-yl(η-1,3-diacet-oxy-5,5-dimethyl-cyclo-hexa-1,3-diene)iron(0).
In the title compound, [Fe(C(12)H(16)O(4))(CO)(3)], the diene moiety of the mol-ecule is virtually planar, with a C-C-C-C torsion angle of -1.4 (2)°. The six-membered ring exhibits a boat conformation, with torsion angles of 46.2 (2) and 46.5 (3)° for a double-bond and the two attached Csp(3) atoms. The Fe atom is coordinated to all four of the diene C atoms, with bond lengths between 2.041 (2) and 2.117 (2) Å. The Fe(CO)(3) tripod adopts a conformation with one CO ligand eclipsing the Csp(3)-Csp(3) single bond.
