In Development of the Anti-Liquid Concept: Justification of a Quantitative Criterion

Key Points

• To establish a quantitative criterion for an anti-liquid based on the coordination number in crystal structures.
• Utilized probability schemes to describe the structure of the coordination sphere of a structural unit in a crystal.
• Developed a mathematical function relating the quantitative criterion to the coordination number.
• Introduced a new criterion for identifying anti-liquid behavior in crystals.
• Provided a framework applicable to classifying both standard and subperiodic crystal structures.
