Students engage in a multi-week, upper-division inorganic laboratory that explores four different metallacrown compounds.  This report provides experimental details regarding the syntheses and characterization techniques, including cyclic voltammetry, solid state magnetic susceptibility, FT-IR, UV-Vis, and paramagnetically shifted 1H-NMR.  In addition, data sets and spectra are provided for the characterization methods.  A general course outline is also provided for the different laboratory sessions.  The premise of the project is to mimic a research laboratory atmosphere in a controlled teaching environment.  The students are expected to explore the primary literature and to develop characterization conditions for their particular metallacrown.  The metallacrown laboratory also serves as a capstone to the inorganic course as multiple lecture topics and laboratory techniques are combined in the last weeks of the semester.  Furthermore, the topic of metallacrowns allows the instructor to combine a variety of principles from other chemistry disciplines such as organic and analytical chemistry.
