Revision Notes — Coordination Compounds
Key concepts, formulas, and definitions from Coordination Compounds for JEE Advanced Chemistry preparation.
Key Topics to Revise
Basic Concepts and Terminology
- Coordination compounds contain a central metal atom/ion bonded to ligands through coordinate bonds
- Double salts completely dissociate in water (e.g., KCl·MgCl₂·6H₂O), while coordination compounds retain their complex ion structure
- Central metal atom/ion accepts electron pairs from ligands (Lewis acid-base interaction)
Types of Ligands
- Monodentate ligands: H₂O, NH₃, Cl⁻, CN⁻, CO (donate one electron pair)
- Bidentate ligands: ethylenediamine (en), oxalate ion (ox²⁻) (two donor atoms)
- Polydentate ligands: EDTA (hexadentate), diethylenetriamine (tridentate)
Nomenclature of Coordination Compounds
- Cation named before anion in complex compounds
- Ligands named alphabetically before metal in coordination entity
- Greek prefixes for ligand numbers: mono-, di-, tri-, tetra-, penta-, hexa-
Isomerism in Coordination Compounds
- Structural isomerism: linkage, ionization, coordination, hydrate isomerism
- Stereoisomerism: geometrical (cis-trans) and optical isomerism
- Geometrical isomerism in square planar [Ma₂b₂] and octahedral [Ma₄b₂] complexes
