Se (X-ray structure reported previously) and 8 where X = Te, [Os6H(Se)(C4H3)(CO)20], 2, [Os2(CO)6(C4H4Se)], 3, [Ru2(CO)6(C4H4)], 4, [Ru4(CO)6(C4H4)], 4, [Ru4(Se)(CO)11(C4H4)], 5, [Fe2(CO)6(C4H4)], 6, and [Fe2(CO)6(C4H4Se)], 7. The clusters 2 and 5 were shown by single-crystal X-ray diffraction methods to have had both SeC bonds broken to give μ3-Se ligands in each case. Compound 2 contains an interesting
