The coordination compounds can be classified into the following types based on the net charge of the complex ion. A coordination compound in which the complex ion
- carries a net positive charge is called a cationic complex.
- Example [Ag (NH3)2]+
- carries a net negative charge is called an anionic complex.
- Example [Ag (CN)2]-
- bears no net charge is called a neutral complex.
- Example [Ni (CO)4]
