The dynamic stereochemistry of endo-(starphenylene)chromiumtricarbonyl, enro-1-Cr, is elucidated through NMR spectroscopic methods. Intramolecular metal-arene migration and hindered metal-tripod rotation are observed in closely related derivatives of enro-1-Cr. The stereochemistry of these systems is modeled well by ab initio local density functional theory methods
