The reaction of As4Se4 with stoichiometric amounts of [Cp$\rm{^{{\ast}}_{2}}$Fe2(CO)4] (Cp*=C5Me5) in boiling toluene forms [Cp$\rm{^{{\ast}}_{2}}$Fe2As2Se2] (1) in good yield. X‐ray crystallography shows 1 to have a triple‐decker structure which comprises a tetraatomic μ,η4:4‐As2Se2 ligand. Density...
