Bis(1-ferrocenylethanone oximato)triphenyl-anti-mony(V)

Area of Science:

• Organometallic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Iron and antimony compounds exhibit diverse coordination geometries and bonding.
• Organometallic complexes with mixed-metal centers are of interest for their unique electronic and structural properties.

Purpose of the Study:

• To elucidate the crystal structure and coordination geometry of a novel iron-antimony complex.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the molecular structure.
• Analysis of bond lengths, angles, and intermolecular interactions was performed.

Main Results:

• The title compound, [Fe(2)Sb(C(5)H(5))(2)(C(6)H(5))(3)(C(7)H(7)NO)(2)], was synthesized and characterized.
• The antimony center displays a distorted trigonal-bipyramidal coordination geometry.
• Three phenyl ligands occupy equatorial positions, while two oxygen atoms from ferrocenylethanone oximate ligands are in axial positions.
• The crystal structure is further stabilized by two intermolecular C-H⋯π interactions.

Conclusions:

• The study provides a detailed structural description of a novel iron-antimony organometallic complex.
• The observed trigonal-bipyramidal geometry around antimony highlights the versatility of antimony coordination in organometallic compounds.
• Intermolecular C-H⋯π interactions play a significant role in stabilizing the crystal lattice.
