(RS)-Tricarbonyl(η4-1,3-diacetoxy-5,5-dimethylcyclohexa-1,3-diene)iron(0)

Abstract

In the title compound, [Fe(C12H16O4)(CO)3], the diene moiety of the molecule 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 Csp3 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 Csp3—Csp3 single bond.
