(E)-1-Ferrocenyl-3-(3-nitro-phen-yl)prop-2-en-1-one

Area of Science:

• Organometallic Chemistry
• Crystallography
• Supramolecular Chemistry

Background:

• Understanding the structural and bonding characteristics of organometallic compounds is crucial for developing new materials and catalysts.
• Cyclopentadienyl (Cp) ligands are fundamental in coordination chemistry, influencing the electronic and steric properties of metal complexes.
• Intermolecular interactions, such as hydrogen bonding and pi-stacking, play a significant role in the self-assembly and solid-state properties of crystalline compounds.

Purpose of the Study:

• To elucidate the detailed crystal structure of the title compound, [Fe(C(5)H(5))(C(14)H(10)NO(3))].
• To analyze the spatial arrangement and relative orientation of the cyclopentadienyl rings and the conjugated substituent.
• To identify and quantify the intermolecular interactions governing the crystal packing.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the three-dimensional molecular structure.
• Crystallographic data was analyzed to assess bond lengths, bond angles, and intermolecular distances.
• Hydrogen bond analysis and pi-pi stacking interactions were quantified using standard crystallographic methods.

Main Results:

• The crystal structure features one substituted and one unsubstituted cyclopentadienyl (Cp) ring, which are nearly parallel and in an eclipsed, ordered arrangement.
• The conjugated substituent exhibits a slight twist relative to the Cp ring.
• Four intermolecular C-H⋯O hydrogen bonds (3.324(3)–3.539(3) Å) and one π(aryl ring)–π (Cp ring) stacking interaction (ring-centroid distance of 3.894(2) Å) were identified.

Conclusions:

• The crystal structure of [Fe(C(5)H(5))(C(14)H(10)NO(3))] is characterized by specific orientations of its Cp ligands and significant intermolecular interactions.
• The observed hydrogen bonding and pi-stacking interactions dictate the overall crystal packing and stability.
• This detailed structural information provides insights into the solid-state behavior of this organometallic complex.
