This problem set was designed to be an in-class activity for students to practice applying their knowledge of metal-metal bonding (as discussed in the previous lecture) to recently published complexes in the literature. In this activity, complexes from four papers by Christine M. Thomas and coworkers are examined to give students practice in electron counting (CBC method), drawing molecular orbitals, and fundamental organometallic reactions.
Following the activity, a student should be able to:
· Determine electron counts and oxidation states of complexes with M-M bonds using CBC electron counting method
· Draw molecular orbital diagrams for M-M bonds
· Determine M-M bond order
· Propose mechanisms for reactions at M-M centers
· Apply fundamental inorganic chemistry to reports in the literature
This was implemented in the second quarter of advanced inorganic chemistry (4th year level) before the second midterm as an in-class group activity. The worksheet generated a lot of interest from the students and generated good discussions in a class of 23 students. In the previous lecture, we discussed basic metal-metal bonding, including drawing MO diagrams and determining bond order for homobimetallic complexes. This worksheet was a reasonable extension, requiring students to apply this knowledge to more complicated systems.
