  1. Coordinate Covalent Bonding Most commonly found as: • Coordination Compounds Chelates

  2. Components of a: coordination COORDINATION COMPOUND • Complex ion • Appropriate cation or anion

  3. CompLEX ION Components • Liganding species(ions or molecules)( hereinafter called ‘particle’) • Transition Metal Ion(also aluminum and lead)

  4. Ligands • Name of bond formed between metal ion and particles • Both bond and particle can be called ligand • Lone pairs on particle attach to metal ion • Particles with more than 1 attachment - chelate • lone pairs must be separated by at least 2 atoms • ethylene diamineoxalate ion acetylacetone • Ligand attachment sites called DENTATES • hemeglobin - Fe chlorophyll - Mg vitamin B12 - Co

  5. Br- Cl- I- Na+ K+ NO3+ SO4-2 Ligand Information H2O NH3 CO2 Monodentates with charges • Monodentates with no charge

  6. Ligand Information ethylenediamine (en) Bidentates with charges • Bidentates with no charge oxalate(ox,or C2O4)-2 tartrate(tar)-2 acetylacetone(acac)-

  7. Ligand Information ethylenediaminetetraacetate (EDTA)- • Hexadentates with charges

  8. Formulas for complex ions Recognized by use of brackets • [Cu(NH4+)4]+6 [Cu(NH3)4]+2 • [Cu(NO2-)4]-2 Coordination number - # of ligands formed (can only be 2,4, or 6) Charge: Metal ion oxidation numbers + ∑ particle charges

  9. Coordination Compounds [ ] = complex ion [Cu(NH4+)4](SO4)3 • [Cu(NH4+)4]Cl6 K2[Cu(NO2-)4] (NH4)2[Cu(NO2-)4]

  10. Coordination # 4 Coordination numbers [Cu(NH4+)6](SO4)4 Coordination # 6 • [Cu(NH4+)4]Cl6 Coordination # 2 (NH4)4[Cu(PO4-3)2]

  11. Coordination numbers Coordination # 4 • [Cu(NH4+) 2(NO3+)2]Cl6 (NH4)4[Cu(ox)3] Coordination # 6 ox is a bidentate
