Area of Science:

• Organometallic Chemistry
• Coordination Chemistry
• Crystallography

Background:

• Understanding the structural nuances of organometallic compounds is crucial for predicting their reactivity and applications.
• The [Fe(C5H5)(C16H12N)] complex presents an interesting case for studying electronic and steric effects within metallocene derivatives.

Purpose of the Study:

• To elucidate the precise three-dimensional structure of the [Fe(C5H5)(C16H12N)] molecule.
• To analyze the spatial arrangement and bonding parameters within the complex, focusing on the cyclopentadienyl rings and the iron center.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular structure.
• Analysis of bond lengths, bond angles, and torsion angles provided detailed structural insights.

Main Results:

• The cyclopentadienyl rings in [Fe(C5H5)(C16H12N)] exhibit an approximately eclipsed conformation with a small inter-planar angle of 0.8(7)°.
• The iron atom is slightly asymmetrically coordinated, with shorter distances to the substituted cyclopentadienyl ring (1.639(2) Å) than the unsubstituted one (1.645(2) Å).
• The C=N double bond is nearly coplanar with the substituted cyclopentadienyl ring (deviation 10.3(1)°), and forms a 47.1(1)° angle with the naphthalene system.

Conclusions:

• The structural analysis of [Fe(C5H5)(C16H12N)] provides a detailed geometric description of this organometallic complex.
• The observed structural parameters, including ring orientation and atom distances, offer insights into the electronic distribution and potential reactivity of the molecule.
