(Cyclooctatetraene)iron tricarbonyl is the organoiron compound with the formula (C8H8)Fe(CO)3. Like other examples of (diene)Fe(CO)3 complexes, it is an orange, diamagnetic solid. Although several isomers are possible, only the η4-C8H8 complex is observed. The complex is an example of a ring-whizzer, since, on the NMR time-scale, the Fe(CO)3 center migrates around the rim of the cyclooctatetraene ligand.[1]
