Focus

  • Structural vs stereoisomerism
  • Cis/trans and fac/mer
  • Lambda/Delta enantiomers
  • Linkage and coordination isomers

Isomerism essentials

  • Structural isomers differ by connectivity.
  • Stereoisomers differ by spatial arrangement.
  • Geometric: cis/trans (square planar, octahedral), fac/mer (octahedral).
  • Optical: Lambda/Delta in tris-chelates and bis-chelates.
