उत्तर
1. Cationic Complexes: A cationic sphere complex is a coordination compound with a positively charged coordination sphere.
For example: \[\ce{[Co (NH3)5Cl] SO4 ⇌ (Co (NH3)5Cl)^{2+} + SO^{2-}_{4}}\]
2. Anionic Sphere Complexes: An anionic complex is a coordination compound with a negatively charged coordination sphere.
For example: \[\ce{[Ni(CN)4]^{2-} K3[Fe(CN)6] ⇌ 3K^{+} + [Fe(CN)6]^{3-}}\]
3. Neutral Sphere Complexes: A neutral coordination complex lacks cationic or anionic spheres.
For example: \[\ce{[Pt (NH3)2 Cl2] , [Ni (Co)4]}\]
