(4-Chloro-3-nitro-benzoato)triphenyl-tin(IV)

Area of Science:

• Organometallic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Organotin compounds exhibit diverse coordination geometries and bonding interactions.
• Understanding the structural nuances of tin complexes is crucial for developing new materials and catalysts.

Purpose of the Study:

• To elucidate the crystal structure and molecular conformation of the title compound, [Sn(C(6)H(5))(3)(C(7)H(3)ClNO(4))].
• To investigate the nature of intra- and intermolecular interactions, including hydrogen bonding and ligand orientation.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the three-dimensional structure of the compound.
• Analysis of bond lengths, bond angles, and intermolecular contacts was performed.

Main Results:

• The tin(IV) atom adopts a distorted tetrahedral geometry coordinated by three phenyl rings and a monodentate carboxylate group.
• An intramolecular C-H⋯O hydrogen bond stabilizes the molecular conformation, forming an S(5) ring.
• The 4-chloro-3-nitro-benzoate ligand exhibits specific dihedral angles with the phenyl ligands, and the nitro group oxygen atoms are disordered.
• Intermolecular C-H⋯O hydrogen bonds link molecules into chains along the [010] direction.

Conclusions:

• The study provides a detailed structural characterization of a novel organotin(IV) complex.
• The observed hydrogen bonding and disorder offer insights into crystal engineering and supramolecular assembly in organometallic compounds.
