Study Notes

Geometric Arrangements of Complexes

Square planar geometry is often associated with a d8 electronic configuration, where the electronic factor strongly favors a square planar arrangement.

Complexes and Conductivity

Complexes can be classified as either electrolytes or nonelectrolytes based on their conductivity.

Mechanisms of Ligand Exchange

The interchange (I) mechanism is a proposed mechanism that combines aspects of the limiting A and D mechanisms.
The interchange (I) mechanism involves the simultaneous entry and departure of two participating ligands.
