5-triene)(η4-cycloocta-1,5-diene)iron(0), 1, stable at low temperature (−30°C), has been prepared by co-condensation of iron atoms with cycloocta-1,5-diene at −196°C followed by condensation of cyclohepta-1,3,5-triene. Complex 1 furnishes, reacting with carbon monoxide and trimethylphosphite, the compounds monocarbonyl(1,4-η-cyclohepta-1,3,5-triene) (η4-cycloocta-1,5-diene)iron(0), 2, and (1-4-η-cyclohepta-1
