"Introduction to Transition Metal Chemistry"

• Isomerism in complexes
  • Stereochemistry of complexes: tris-chelates: Δ and Λ isomers, tetrahedral and octahedral stereoisomers
• The importance of d orbitals in transition metal chemistry
  • d electron count, oxidation number and oxidation state
  • Magnetochemistry: spin states of d electrons

• $\mu _{\text{obs}}=2.83{\sqrt {\chi _{m_{\text{corr}}}T}}$
  
  
• $\mu _{S}=g{\sqrt {S\left({S+1}\right)}}={\sqrt {4S\left({S+1}\right)}}{\text{ BM}}$
  
  
• $\mu _{S}={\sqrt {n\left({n+2}\right)}}$
  
  
• $\mu _{S+L}={\sqrt {4S\left({S+1}\right)+L\left({L+1}\right)}}={\sqrt {n\left({n+2}\right)+L\left({L+1}\right)}}$

• Crystal field theory
  • $\Delta _{\text{t}}\approx {\frac {4}{9}}\Delta _{\text{o}}$
• Spectrochemical series: I⁻ < Br⁻ < Cl⁻ < F⁻ < OH⁻ < H₂O < NH₃ ≈ py < en < bpy < PR₃ < CN⁻ ≈ CO
