Ionic Geometry
What is Ionic Geometry?
Ionic geometry refers to the three-dimensional arrangement of ions in an ionic crystal lattice, determined by the relative sizes of the cations and anions (radius ratio) and the requirement to maximize electrostatic attraction while minimizing repulsion. Common ionic geometries include the rock salt structure (NaCl), the cesium chloride structure (CsCl), and the zinc blende structure (ZnS). The coordination number and geometry are fundamental in predicting and explaining the physical properties of ionic solids.
