Write the coordination number and molecular geometry for diamminesilver (l) dicyanoargentate.

1 answer

Diamminesilver(I) dicyanoargentate refers to the coordination complex with the formula [Ag(NH₃)₂][Ag(CN)₂]. In this complex, the silver ion is coordinated in two different ways.

  1. Coordination Number: The coordination number of the silver ions in this complex is 2. The first silver ion is coordinated to two ammonia (NH₃) ligands, while the second silver ion is coordinated to two cyanide (CN⁻) ligands.

  2. Molecular Geometry:

    • For the diamminesilver(I) component ([Ag(NH₃)₂⁺]), the geometry is linear, as it is a coordination complex with a coordination number of 2.
    • For the dicyanoargentate (CN) moiety ([Ag(CN)₂⁻]), the geometry is linear as well.

In summary, both parts of the complex exhibit linear geometry due to their coordination of two ligands.
