1-Acetyl-5-ferrocenyl-3-phenyl-2-pyrazoline.

Area of Science:

• Organometallic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Understanding the structural nuances of organometallic compounds is crucial for predicting their reactivity and properties.
• Iron complexes with heterocyclic ligands offer diverse applications in catalysis and materials science.

Purpose of the Study:

• To elucidate the three-dimensional molecular structure of the iron complex [Fe(C(5)H(5))(C(16)H(15)N(2)O)] through single-crystal X-ray diffraction.
• To analyze the conformational preferences and intermolecular interactions within the crystal lattice.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the precise atomic arrangement.
• Crystallographic analysis was performed to identify bond lengths, angles, and intermolecular forces.

Main Results:

• The pyrazoline and phenyl rings exhibit near coplanarity (dihedral angle of 6.54°).
• The substituted cyclopentadienyl ring is significantly twisted (81.32°) relative to the pyrazoline ring.
• Weak intermolecular hydrogen bonds (C-H⋯O) and C-H⋯π interactions stabilize the crystal structure.

Conclusions:

• The study provides a detailed structural characterization of the iron complex.
• The observed molecular geometry and intermolecular interactions offer insights into the solid-state behavior of this organometallic compound.
