When teaching reactions and mechanisms of inorganic complexes, I tend to get to the end of the chapter (out of breath) and find myself thinking "*$#&, I forgot about electron transfer". While I think it is important that students get an understanding of this in an upper level inorganic course, I simply don't have, or forgot to budget the time to really talk about it.
I give them a brief rationale for why one would want to study mechanisms of electron transfer ("Remember all those redox reactions you balanced back in first year? Are you curious how those electrons moved around?"), and hand out/refer them to an excellently written retrospective on the career and research of Henry Taube (see link below).
I found this Inorganic Chemistry Viewpoint article to be very "readable", without sacrificing chemical detail (the nitty gritty). I breifly highlight some of the interesting points (Co3 + Cr2 --> Co2 + Cr3), and encourage them to read on to learn more about the career of a Nobel Prize winning inorganic chemist.
Students should gain an understanding of the mechanisms for electron transfer. One of the other main goals for this reading is to have the students learn and appreciate the history of the field. I try to highlight the logical progression of research goals, and this article demonstrates the influence of Taube's early years on the research conducted later.
Students seem to like the article. Many comment that Henry Taube has an extraordinary moustache!
