Question
Explain the types of complexes based on the charge on the complex.
✓
Answer
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 $\left[ Ag \left( NH _3\right)_2\right]^{+}$
- carries a net negative charge is called an anionic complex. Example $\left[ Ag ( CN )_2\right]^{-}$
- bears no net charge is called a neutral complex. Example $\left[ Ni ( CO )_4\right]$
- carries a net positive charge is called a cationic complex. Example $\left[ Ag \left( NH _3\right)_2\right]^{+}$
- carries a net negative charge is called an anionic complex. Example $\left[ Ag ( CN )_2\right]^{-}$
- bears no net charge is called a neutral complex. Example $\left[ Ni ( CO )_4\right]$
