Coordination Compounds Part 2

[Ag(NH3)2][Ag(CN)2] complex dissociates into [Ag(NH3)2]+ and
[Ag(CN) ].
Oxidation of Ag in [Ag(NH3)2]+
Ag + 0 × 2 = + 1
Ag = + 1
Oxidation state of Ag in [Ag(CN)2]−
Ag + (−1) × 2 = −1
Ag − 2 = −1
⇒ Ag = + 1
∴ Sum of oxidation states of two silver ions in
[Ag(NH3)2][Ag(CN)2] complex is 2.
