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

Answer 1

The compound you are referring to is diamminesilver(I)dicyanoargentate(I), which can be represented as \([Ag(NH_3)_2][Ag(CN)_2]\).

In this complex:

1. Coordination Number:

   • For the silver ion coordinated with two ammonia (\(NH_3\)) ligands, the coordination number is 2.
   • For the silver ion associated with two cyanide (\(CN^-\)) ligands, the coordination number is also 2. Therefore, both silver ions have a coordination number of 2.

2. Geometry:

   • The geometry of a coordination complex with a coordination number of 2 is typically linear. Therefore, the geometry around each silver ion in this complex is linear.

In summary, for diamminesilver(I)dicyanoargentate(I):

• Coordination Number: 2 for each silver ion
• Geometry: Linear for each silver ion.
