Werner’s Theory of Coordination Compounds General introduction to salts, difference between double salt and coordination (complex salt) compound with respect to their ionization in water, with an example. Werner’s theory – postulates, limitations.
Definitions of Some Important Terms Pretending to Coordination Compounds Coordination entity, central metal ion, coordination number, coordination sphere, oxidation state of central metal ion, homoleptic and heteroleptic complexes, examples.
Nomenclature of Coordination Compounds Nomenclature of coordination compounds – mononuclear compounds.
Isomerism in Coordination Compounds Isomerism: Structural – linkage, ionization, solvate, coordination – definition and examples. Stereoisomerism – geometrical and optical, examples, facial and meridional as geometrical isomers- example.
Bonding in Coordination Compounds VBT: salient features, application of VBT for the formation of – [CoF6] 3, [Co (NH3)6] 3+, [NiCl4] 2, [Ni (CN)4] 2. magnetic properties – low spin and high spin complexes with examples, limitations of VBT. CFT (crystal field theory): crystal field splitting-meaning, crystal field splitting in octahedral and tetrahedral coordination entities using energy level diagram and their comparison. Spectrochemical series, compare weak field ligand – strong field ligand with respect to d4 ions in octahedral field (0 < P, 0 > P). Explanation for colour of complexes using CFT, examples.
