This paper is a meaty communication that covers novel bonding of 4 e- π-donors to a 14-electron species. Requires students to apply their knowledge of electron counting and organometallic bonding to ligands that are acting in novel ways. This also includes exercises dealing with chemical information and general questions that require students to put the science in context.
This experiment is a computational supplement to Part B of the tin chemistry described in "Synthesis and Technique in Inorganic Chemistry" (Exp 7; see below for the complete citation).* Students will optimize and compute IR spectra for the cis and trans and corresponding linkage isomers of tetrachlorbis(dimethylsulfoxide) tin(IV). A comparison of experimental (IR spectra) and computational data (enthalpies of formation; IR spectra) will aid them in determining the most likely product of this simple synthesis and in identifying the S-O vibrations in their experimental spectrum.
This is a computational/molecular modeling supplement to the synthesis of [1,3,5-C6H3(CH3)3]MoCO3 included in the third edition of "Synthesis and Technique in Inorganic Chemistry" (see full citation below)*. Students optimize the model and compute an infrared spectrum and compare it to their experimental (solution) spectrum.

The students prepare a short proposal outlining their desired target and why they want to make it. Chemicals are ordered, and during the last 3-4 weeks of the semester, the students carry out their synthesis. The writeup is as a paper submtited to the journal Inorganic Chemistry using the template from the journal web page.
