Coordination compounds ... So complex?
Keywords:
complex, chelates, ligand, central ionAbstract
Coordination complexes are compounds whose molecular structure is generally formed by a central element that has unoccupied valence orbitals, surrounded by a number of molecules or ions that have pairs of unshared electrons, capable of forming different types of bond. In this paper we present the basic principles of the chemistry of coordination compounds, including their nomenclature. The agronomic importance of this type of compounds, either in plant physiology or when used as fertilizers to provide essential nutrients to plants is emphasized.
