CHAPTER 22 - Coordination Compounds 1. Metal Complexes a) metal - Lewis acid (accepts e pair) b) ligand - Lewis base (donates e pair) c) coordinate covalent bond 2. Ligands name, formula, charge, # of donor atoms 3. Nomenclature (complex: name formula) 4. Isomers (same formula, different structure) - stereoisomers a) geometric - cis / trans b) optical - enantiomers ( chiral - non- superimposable mirror images) 5. Valence Bond Theory shape, hybridiza- tion, magnetism (need high/low spin) 6. Crystal Field Theory ( d e ’s t 2 g / e g )- add spectrochemical series to explain a) color b) magnetic properties 7. Ligand Field Theory (CF + MO) - explains everything (bonding)

Unformatted text preview: Bonding and Properties Valence Bond Theory 1. shape and bonding (hybridization) - explains 2. magnetism - sometimes incorrect 3. color - no insight Crystal Field Theory (spectrochemical series) 1. magnetism and color - crystal field splitting (octahedral: d e s t 2 g / e g set) 2. bonding - no insight Ligand Field Theory (CF + MO)- explains everything, e.g. , 1. what is analogous to the "stable octet" (# of valence electrons) => bonding, nonbonding, antibonding MOs 2. why the spectrochemical series a) only bonding ligands b) and bonding ligands filled p orbitals empty p orbitals...
