Title 4499798

  • ChemDraw drawings

  • in ChemDraw, use ACS settings

  • copy drawing to presentation and reduce size to 90%

  • One X-ray structure per slide

  • Tables showing only minimal/necessary data

  • Spectra made with Origin

  • Use 2 pt line thickness in Origin

  • Reduce graph size in presentation to 70%


Chemistry and properties of ln iii

Chemistry and properties of Ln(III)

  • Oxidation state +III is most common

  • Hard acids

  • Prefer hard donor atoms O>N>>P,S

  • Large cations

  • Large coordination numbers

    • Core 4f electrons

    • Omnidirectional/ionic bonding

    • Coordination numbers dictated by steric bulk of ligands

  • Similar ionic radii

  • Magnetism

  • Light emission due to f-f transitions

    • Core 4f orbitals

    • Characteristic emission colors

    • Sharp emission bands

    • f-f transitions forbidden by selection rules

CN 6:

rion Ce3+=115.0 pm

rion Lu3+=100.1 pm
