Abstract
In the molecule of the title cluster compound, mu(4)-selenido-bis [mu- (4-tolylselenido)-hexacarbonyldiiron], two identical (mu-4-CH3C6H4Se)F e-2(CO)(6) moieties are joined by a spiro-type four-coordinate Se atom , mu(4)-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) Angstrom. The average ( 2.353 Angstrom) is shorter than that (2.392 Angstrom) of Se-Fe bond le ngths formed between Fe atoms and the 4-tolylselenido ligands. In each diiron subcluster core, the 4-tolylselenido ligand is bridged between two Fe atoms.
