Edexcel IAL Chemistry A2 17.5 dative covalent bonding in complexes
Look for a lone pair on the ligand atom, then show or name the coordinate bond donated to the metal ion in complexes such as platinum, nickel or copper.
How this is tested
- Describe ligand binding as lone-pair donation to a central metal ion in a complex.
- Draw or identify dative covalent bonds from O or N donor atoms to Ni2+ or Pt2+.
- Distinguish dative covalent bonding in complexes from ionic or ordinary covalent bonding.
