The structure of the singlet state ( 1 A 1 ) of [Fe(CO) 4 ] in the gas phase (see picture) has been determined by a combination of laser photochemistry of [Fe(CO) 5 ] and electron diffraction imaging. The ground state of [Fe(CO) 4 ] is known to be a triplet species ( 3 B 2 ), and this is the species detected in picosecond time‐resolved IR experiments with [Fe(CO) 5 ] in solution. This is an appropriate moment to survey the state of knowledge on [Fe(CO) 4 ], beginning from the first low‐temperature matrix experiments.
