This exercise looks at the metal complexes of tropocoronand ligands, which were first studied by Nakanishi, Lippard, and coworkers in the 1980s. The size of the metal binding cavity in these macrocyclic ligands can be varied by changing the number of atoms in the linker chains between the aminotroponeimine rings, similar to crown ethers. These tetradentate ligands bind a number of +2 metal centers (Cd, Co, Cu, Ni, and Zn) and the geometry of the donor atoms around the metal center changes with the number of atoms in the linker chains.

For twenty years, I have started my second-year Inorganic Chemistry class with a few PowerPoint slides illustrating the inorganic chemistry that is present in a number of societal areas. The point is to emphasize to the students that inorganic chemistry is present in all aspects of life. To make this process more interactive, I made "game pieces" with a topic on the front (e.g, photography or radiation protection or vitamin B12) and an area on the back (energy, materials, biology, medicine, or environment). As each student enters the class, they are asked to take one game piece.

I do not like to take a large amount of time in class to cover nomenclature of any kind, though I want students to know the names of common ligands and the basic ideas of how coordination complexes are named.  Since it is a systematic topic I assign this guided inquiry worksheet.  I guess I think about it like learning rules for a new board game, sometimes you just have to play and learn as you go.  This assignment is meant to establish teh basica rules for naming by guiding students through what the needs are in naming, then it allows them to identify the convetions from a list of structur

This in-class activity is designed to assist students with the visualization of solid-state close-packed structures, using metal-sulfide nanocrystalline materials as a an example system.
