Coordination coordination complex

A coordination complex is a chemical structure formed when a central metal atom, often a transition metal, bonds with several surrounding molecules or ions called ligands. These ligands donate pairs of electrons to the metal, creating a stable complex. This arrangement gives coordination complexes unique properties, making them important in various fields, including catalysis, material science, and biology. For example, hemoglobin, which carries oxygen in the blood, is a coordination complex. The way these complexes are structured influences their behavior and function in different chemical reactions and processes.
