Examples of Square Planar Transition Metal Complexes:
Ni(II)
(mainly d8) Rh(I) Pd(II)
Ir(I) Pt(II) Au(III)
General Rate Law:
Factors Which Affect The Rate Of Substitution
1. Role of the Entering Group
2. The Role of The Leaving Group
3. The Nature of the Other Ligands in the Complex
4. Effect of the Metal Centre
