Abstract
The main structural feature of the title compound, [Fe(C7H8NO)(C7H7O2)], is the existence of the strong intermolecular hydrogen bond of the N—H⋯O=C type between the amide N—H group and the carbonyl O atom of the COOCH3 group from an adjacent molecule [2.934 (2) Å]. The acetamide O atom participates as a double proton acceptor in intermolecular hydrogen bonds of type C—H⋯O [3.411 (2) and 3.506 (2) Å], thus forming a three-dimensional network. The cyclopentadienyl rings, which are parallel to each other within 1.04 (9)°, are twisted from the eclipsed conformation by only 3.92 (1)° (maximum). The acetamido, NHCOCH3, and ester, COOCH3, groups are not in the plane of the cyclopentadienyl rings to which they are attached [dihedral angles are 14.55 (10) and 7.64 (9)°, respectively]. The deviation from coplanarity is attributed to the intermolecular hydrogen bonds.
