Structure and Nomenclature of Coordination Compounds

  • Page ID
  • Coordination chemistry is the study of compounds formed between metal ions and other neutral or negatively charged molecules such as [Co(NH2CH2CH2NH2)2ClNH3]2+ Cl22-. In this formulation, Co(NH2CH2CH2NH2)2ClNH3]2+ is known as a metal complex, which is a charged species consisting of metal ion bonded to one or more groups of molecules. The bonded molecules are called ligand. The little picture shown here depicts a structure of a 6-coordinated complex.
