My Notes

This is a short set of slides I use to introduce aspects of coordination chemistry for my foundation level inorganic chemistry class. 

Learning Goals

Students should be able to:

  • Define the terms "primary valence" and "secondary valence"
    • Translate these terms to modern concepts of oxidation state and coordination numbers.
    • Relate the secondary valence of a metal to the inner coordination sphere of the coordination complex
  • Use the Chain Theory espoused by Blomstrand and Jorgensen to account for the observed ratios of Co and NH3 in cobalt ammonates
  • Apply Chain Theory to predict the ease of precipitation of chloride ions from metal complexes
  • Predict the number of isomers expected for six-coordinate complexes with hexagonal planar, trigonal prismatic, or octahedral shapes
  • Draw a chiral coordination complex, and demonstrate that it is the non-superimposable mirror image of it's enantiomer
Implementation Notes

Notes for implementation are included in the presenter notes section of each slide. 

Images used in these slides are all public domain, or no attribution required.

Time Required
I devote one class period (~50 minutes) to this
Evaluation Methods

Typically evaluated using related quiz or exam questions about chain theory and the concept of valence. I can create a separate LO with past exam questions and link it here.

This is really good timing as I needed a 5-slides about Werner for an online class I am teaching soon. One thing to note, the non-carbon-containing chiral cation Werner resolved was originally prepared by Jørgensen.

Thanks @Adam I haven't made that note before, but it is a really good one to include. Glad the slides are helpful!

Brad, I am going to adapt this as well. I traditionally cover this in class, but I am going to edit your slides a bit and make a pre-class video. I will let you know once it is complete! Thanks for the great set of slides!
