General Chemistry - Coordination Chemistry | Coordinate Covalent Bond | 21.1 General Chemistry

Chad provides an introduction to Coordination Chemistry in this lesson. The topic revolves around the coordinate covalent bond which is formed between a central metal ion acting as a Lewis acid and one or more ligands acting as Lewis bases in the formation of what are called complex ions and coordination compounds. A list of the most common ligands is presented. The coordination number is the number of bonds made to the central metal ion, and the most common coordination numbers of 2, 4 and 6 are discussed. For a coordination number of 2 the geometry is linear. For a coordination number of 4 there are two possible geometries: square planar and tetrahedral. For a coordination number of 6 the geometry is octahedral. Polydentate ligands are also discussed which can form more than one bond to a central metal ion. They are also commonly referred to as chelating agents, and complexes formed between metal ions and polydentate ligands are often referred to as metal chelates.
