Coordination Geometry

Coordination geometry refers to the spatial arrangement of atoms or molecules around a central atom or ion in a chemical compound. Think of it like seating arrangements at a round table, where the central atom is the host and the surrounding atoms or molecules are guests. The way these guests are positioned—whether in a straight line, a triangle, a square, or other shapes—determines the coordination geometry. This geometry influences the chemical properties and behavior of the compound, such as reactivity and stability. Common types include octahedral, tetrahedral, and linear arrangements.
