From the room-temperature reaction of the mixed-chalcogenide compound Fe2(CO)6(μ-SeTe) with phenylacetylene two isomeric products were isolated, Fe2(CO)6{-SeC(H)=C-(Ph)Te} (1) and Fe2(CO)6{μ-SeC(Ph)=C(H)Te} (2). Fe2(CO)6(μ-SSe) reacted with phenylacetylene to form Fe2(CO)6{μ-SC(Ph)=C(H)Se} (3). The room-temperature reaction of Fe2(CO)6(μ-STe) with phenylacetylene also yielded two isomeric products, Fe2(CO)6(μ-SC-(H)=C(Ph)Te) (4) and Fe2(CO)6(μ-SC(Ph)=C(H)Te) (5). In all of these reactions, the homochalcogenide compounds Fe2(CO)6(μ-EC(H)=C(Ph)E) (E = Se, Te, E = S, Se, and E = S, Te, respectively) were also formed in trace amounts. The new compounds 1-5 were characterized by IR and 1H, 13C, 77Se, and 125Te NMR spectroscopy. Compound 1 was structurally characterized by single-crystal X-ray diffraction methods. It crystallized in the triclinic space group P1 with a = 7.773(9) A?, b = 10.635(9) A?, c = 12.010(10) A?, α = 104.99-(10)°, β = 102.86(11)°, γ = 106.38(9)°, V = 872.1(8) A?3, Z = 2, and D(calc) = 2.241 g cm-3. Full-matrix least-squares refinement of 1 converged to R = 0.077 and Rw = 0.086.
Addition of alkynyllithium reagents to the S-S bond of (μ-dithlo)bis(tricarbonyliron): Equilibria between open S-centered and bridged C-centered anions

Alkynyllithium reagents cleave the S-S bond of (μ-S2)Fe2(CO)6 to give (μ-RC≡CS)(μ-LiS)Fe2(CO)6 complexes which apparently are in equilibrium with products of intramolecular S- addition to t
