In the molecule of the title cluster compound, μ4-selenido-bis[μ-(4-tolylselenido)-hexacarbonyldiiron], two identical (μ-4-CH3C6H4Se)Fe2(CO)6 moieties are joined by a spiro-type four-coordinate Se atom, μ4-Se. The four Se—Fe bond lengths around the central Se atom are 2.353 (3), 2.353 (3), 2.347 (3) and 2.358 (3) Å. The average (2.353 Å) is shorter than that (2.392 Å) of Se—Fe bond lengths formed between Fe atoms and the 4-tolylselenido ligands. In each diiron subcluster core, the 4-tolylselenido ligand is bridged between two Fe atoms.
