Abstract

The compound Ru4(CO)114-Te)2(1) has been prepared by refluxing a benzene solution containing Fe3(CO)93-Te)2and Ru3(CO)12. The compounds Ru3(CO)6(PPh3)33-Te)2(2) and Ru4(CO)10(PPh3)(μ4-Te)2(3) were obtained from the room-temperature reaction of 1 with PPh3. Similarly, Ru4(CO)9(μ-Ph2PCH2PPh2)(μ4-Te)2(4) was obtained from the reaction of 1 with Ph2PCH2PPh2at room temperature. The structure of 1–4 were established by single-crystal X-ray diffraction analysis. Crystal data: 1, orthorhombic, Pccn, a = 6.924 (2) Å, b = 16.289 (6) Å, c = 18.054 (6) Å, V = 2036 (1) Å3, Z = 4, R(F) = 4.16%; 2, monoclinic, P21/n, a = 10.539 (4) Å, b = 27.39 (1) Å, c = 20.415 (7) Å, β = 94.96 (3)°, V= 5870 (4) Å3, Z = 4, R(F) = 4.96%; 3, orthorhombic, Pbca, a = 19.070 (5) Å, b = 18.157 (4) Å, c = 19.272 (5) Å, V= 6673 (3) Å3, Z = 8, R(F) = 3.65%; 4, triclinic, P1, a = 13.255 (3) Å, b = 17.610 (5) Å, c = 19.189 (5) Å, α = 65.39 (2)°, β = 78.25 (2)°, γ = 84.13 (2)°, V = 3986 (2) Å3, Z = 4, R(F) = 2.97%.
