trans-Tris(4-bromo-phen-yl)dichlorido-antimony(V)

Area of Science:

• Inorganic Chemistry
• Crystal Engineering
• Supramolecular Chemistry

Background:

• Antimony(V) compounds exhibit diverse coordination geometries.
• Halogenated aromatic ligands offer opportunities for supramolecular assembly.
• Understanding crystal packing is crucial for materials science.

Purpose of the Study:

• To characterize the crystal structure of [SbCl2(C6H4Br)3].
• To investigate the role of intermolecular interactions in the solid-state arrangement.
• To explore the formation of extended networks through hydrogen bonding.

Main Methods:

• Single-crystal X-ray diffraction analysis.
• Structural elucidation of antimony(V) coordination complexes.
• Analysis of hydrogen bonding networks (C-H...Br and C-H...Cl).

Main Results:

• The antimony(V) center adopts a trigonal-bipyramidal geometry.
• Bromo-phenyl groups occupy the equatorial positions, and chloride ions are axial (trans).
• Intermolecular C-H...Br interactions form zigzag chains, while C-H...Cl interactions yield cyclic dimers and a 3D network.

Conclusions:

• The crystal structure of [SbCl2(C6H4Br)3] is determined by a combination of coordination geometry and hydrogen bonding.
• The identified hydrogen bonding patterns lead to the formation of intricate supramolecular architectures.
• This work contributes to the understanding of crystal engineering principles in antimony halide complexes.
