In chemistry, a coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal-containing compounds, especially those of transition metals, are coordination complexes. A coordination complex whose centre is a metal atom.

Figure 1. You have already learned that a covalent bond forms when electrons are shared between atoms. A coordinate-covalent bond (represented by a green arrow in this diagram) forms when both of the shared electrons come from the same atom, called the donor atom (blue). An anion or molecule containing the donor atom is known as a ligand.

Chemically, the metals differ from the nonmetals in that they form positive ions and. i.e., enter into a chemical reaction; e.g., iron rusts when exposed to moist.

In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base. Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). These component ions can be inorganic, such as chloride (Cl −), or organic, such as acetate (CH

For example, the electron number (EN) of the metal in [ML l X x Z z], i.e. the electron count, is given by EN = m + 2l + x, where m is the number of valence electrons on the neutral metal atom. The valence number (VN) of the metal center, i.e. the number of electrons that the metal uses in bonding, is VN = x + 2z. In most organotransition metal complexes, the number of Z ligands in the.
