Coordination Complexes

Coordination complexes are formations where a central metal atom or ion is bonded to surrounding molecules or ions called ligands. These ligands donate electron pairs to the metal, creating a stable structure. Think of the metal as a core connected to multiple "arms" (ligands) holding onto it. This arrangement influences the complex's chemical properties, color, and reactivity. Coordination complexes are common in many fields, including medicine (like in certain drugs), industry, and biological systems such as hemoglobin in blood. They are fundamental in understanding how metals interact with other molecules in various chemical processes.
