Indium tellurium trioxide chloride, InTeO3Cl

Area of Science:

• Inorganic Chemistry
• Solid-State Chemistry
• Crystallography

Background:

• Indium and tellurium compounds are of interest for their diverse properties.
• Oxychlorides represent a class of materials with unique structural motifs.
• Understanding new material structures is crucial for potential applications.

Purpose of the Study:

• To synthesize a novel indium tellurium oxychloride compound.
• To elucidate the crystal structure of the new material.
• To characterize the bonding and structural features of InTeO(3)Cl.

Main Methods:

• Synthesis of InTeO(3)Cl from In(2)O(3), InCl(3), and TeO(2).
• Single-crystal X-ray diffraction for structural determination.
• Analysis of coordination polyhedra and linking motifs.

Main Results:

• The new compound InTeO(3)Cl was successfully synthesized.
• The crystal structure reveals a layered arrangement.
• Layers consist of edge-sharing [InO(4)Cl(2)] octahedra and [TeO(3)] trigonal pyramids.
• A van der Waals gap separates the layers, with no interstitial chlorine.

Conclusions:

• The novel indium tellurium oxychloride, InTeO(3)Cl, possesses a unique layered structure.
• The structure is built from interconnected inorganic polyhedra.
• The absence of free chlorine between layers influences the material's properties.
