Rock salt structureRelated: Each ion in this structure has six nearest neighbors.
Atomic radiusRelated: Neighbor counts and geometry affect radius assignments in solids.
Hydration shellRelated: It describes the number of waters directly coordinated to an ion.
Covalent radiusRelated: Local bonding environment can affect measured distances and reported radii.
Vacancy defectRelated: Removing an atom changes the local coordination around its former site.
Granular packingRelated: Contact count helps determine whether a packing can resist applied forces.
Network solidRelated: It describes how many bonded neighbors each atom has within a network.
