Discussion Overview

The discussion revolves around the carbon-silver-carbon angle in the complex ion [Ag(CN)2]−, exploring its geometry and bonding characteristics. Participants examine whether the structure is ionic or covalent and how this affects the angle.

Discussion Character

  • Homework-related, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant claims the carbon-silver-carbon angle is 180 degrees but questions the reasoning behind this, suggesting confusion about the nature of the complex ion.
  • Another participant references external sources, suggesting that understanding 'cyanide' and 'p orbital' may provide valuable information regarding the geometry.
  • A different participant cites a source stating that dicyanides are linear in geometry, questioning how the bonding leads to a 180-degree angle if the ligands are bonded to the metal ion.
  • One participant clarifies that the bond between the CN− ions and the Ag+ ion is covalent, asserting that [Ag(CN)2]− is a coordination complex, which may influence the angle.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the bonding in [Ag(CN)2]− and its geometric implications, indicating that the discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Participants have not reached a consensus on the bonding type (ionic vs. covalent) or its implications for the geometry of the complex ion.

Homework Statement


What is the carbon-silver-carbon angle in the complex ion [Ag(CN)2]-??


Homework Equations





The Attempt at a Solution


The answer is 180 degrees why? I thought that complex ion is a ionic compound? If so, how would the shape be like? Thanks.

Hello,
please have a look at 'cyanide' and 'p orbital' for details..on wiki
hopefully you will valuable information.
 
Oh...
"the dicyanides [M(CN)2]− (M = Cu, Ag, Au), which are linear in geometry." from wiki
But why? M is the ligand and both CN- are bonded with M. So the ionic bond in between them is at 180 degrees?
 
The bond between the CN- ions and the Ag+ ion is not ionic, but covalent. The complex ion [Ag(CN)2]- is a coordination complex.
