Edexcel IAL Chemistry A2 17.14 tetrahedral transition-metal complexes
Use the ligand size and coordination number: large chloride ligands often give four-coordinate tetrahedral complexes with about 109.5° bond angles.
How this is tested
- Identify tetrahedral complexes such as [CuCl4]2- or chloro cobalt complexes.
- Explain four-coordination by large chloride ligands causing steric hindrance.
- Draw optical isomers when a tetrahedral metal centre has four different ligands.
