Composition Formulas of Inorganic Compounds in Terms of Cluster Plus Glue Atom Model

Area of Science:

• Inorganic Chemistry
• Materials Science
• Solid-State Chemistry

Background:

• Traditional molecular models are insufficient for describing inorganic structures.
• Metallic glasses and quasi-crystals exhibit complex local atomic arrangements.
• Understanding local atomic configuration is key to inorganic compound properties.

Purpose of the Study:

• To identify and characterize molecule-like structural units in inorganic compounds.
• To apply the "cluster plus glue atom model" to inorganic materials.
• To investigate the applicability of the octet electron rule in inorganic chemistry.

Main Methods:

• Application of the "cluster plus glue atom model" ([cluster](glue atoms)).
• Analysis of nearest-neighbor clusters and outer-shell glue atoms.
• Examination of valence electron counts in inorganic compounds.

Main Results:

• The cluster plus glue atom model successfully identifies molecule-like structural units.
• Inorganic compounds, including fluorides, oxides, and nitrides, adhere to an octet electron rule.
• The total valence electrons per formula unit are consistently multiples of eight.

Conclusions:

• The "cluster plus glue atom model" provides a new perspective on inorganic structures.
• An octet electron rule governs the electron distribution in many inorganic compounds.
• This model offers insights into local atomic configuration, composition, and electron counts.
