(Cyclooctatetraene)iron tricarbonyl

(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.
