Solution

On the basis of charge on complex ion, coordination complex is classified as:

i. Cationic complex: A positively charged coordination sphere or a coordination compound having a positively charged coordination sphere is called the cationic complex or cationic sphere complex.

e.g. [Zn(NH3)4]2+

ii. Anionic complex: A negatively charged coordination sphere or a coordination compound having a negatively charged coordination sphere is called an anionic complex or anionic sphere complex.

e.g. [Zn(CN)6]3–

iii. Neutral sphere complexes: A coordination complex that does not possess a cationic or anionic sphere are neutral complexes of neutral sphere complexes.

e.g. [Ni(CO)4]
