Abstract The complexes Co3(CO)9(μ 3-X) (X=S, Se) can be reduced to the corresponding anionic species [Co3(CO)9(μ 3-X)]−, which react with allyl bromide to give Co3(CO)7(μ-η 3-C3H5)(μ 3-X) (X=S, Se). These are the first two cobalt complexes containing the bridging μ-η 3-allyl ligand. The structure of the selenium complex was determined by X-ray crystallography. Crystal data for Co3(CO)7(μ-η 3-C3H5)(μ 3-Se) are as follows: space group P21/c, a=9.051(2) Å, b=8.102(2) Å, c=21.27(4) Å, β=93.82(3)°, Z=4, and R=0.0565 for 2491 observed reflections.
