(2-Carbamoylethyl-κC,O)triiodidotin(IV).

Area of Science:

• Inorganic Chemistry
• Crystallography
• Materials Science

Background:

• Tin(IV) complexes are of interest due to their diverse coordination geometries and potential applications.
• Understanding the structural features of organotin halides provides insights into chemical bonding and intermolecular interactions.
• Carbamoylethyl ligands offer unique coordination modes in metal complexes.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, [Sn(C(3)H(6)NO)I(3)].
• To analyze the coordination geometry around the tin(IV) center.
• To investigate the intermolecular hydrogen bonding interactions in the solid state.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Structural analysis focused on coordination geometry, bond lengths, and angles around the tin atom.
• Hydrogen bonding networks were identified and characterized using crystallographic data.

Main Results:

• The asymmetric unit contains two independent, virtually identical molecules of [Sn(C(3)H(6)NO)I(3)].
• The tin(IV) atom exhibits a distorted trigonal bipyramidal coordination geometry with a chelating carbamoylethyl ligand (C(1),O-bidentate) and three iodine atoms.
• The carbonyl oxygen atom is positioned trans to a longer Sn-I bond.
• N-H⋯O hydrogen bonds link molecules into an eight-membered amide synthon.
• N-H⋯I hydrogen bonds are also observed between neighboring molecules.

Conclusions:

• The study provides a detailed structural characterization of a novel tin(IV) complex.
• The observed hydrogen bonding patterns highlight the importance of intermolecular forces in directing crystal packing.
• The findings contribute to the understanding of structure-property relationships in organotin compounds.
