Coordination Chemistry - Transition Metal (Ion) Complexes

This video introduces a third type of chemical compound (which has both Covalent Bonding and Ionic Bonding properties). A metal ion (usually a transition metal) in solution, can be "coordinated" by Ligands, which are anions, or neutral molecules with Lone Pairs of electrons that are attracted to the positively charged metal ion. Ligands can have only one donor atom (monodentate) or two donor atoms (bidentate), or more. Dentate (meaning teeth) describes the ligand "biting" the central metal ion. The shape discussed is an octahedral geometry (6 vertices) that the donor atom of the ligands take when the coordination number of the metal is 6. When the coordination number is 4, then either a tetrahedral or square planar geometry is observed, which will be discussed on a subsequent video.
