摘要

Oxidative addition of diphenyl ditellurides to organometallic fragment [Mn(CO)5] produced cis-[Mn(CO)4−(TePh)2]. This complex crystallized in monoclinic space group P21/n with a = 12.876(6) Å, b = 18.001(7) Å, c = 18.670(7) Å,β = 93.77(3)°, V= 4318(3) Å3, Z = 4, final R = 0.035, and Rw = 0.034. Thermolytic conversion of cis-[Mn(CO)4(TePh)2− to [(CO)3Mn(μ-TePh)3Mn(CO)3] was accomplished in high yield by refluxing [Mn(CO)4(TePh)2− in THF solution. Crystal data: triclinic space group P1, a = 10.820(2) Å, b = 15.038(4) Å, c = 19.697(7) Å, a = 107.67(3)°, β = 96.23(3)°, γ = 107.63(2)°, V = 2838(1) Å3, Z = 2, R = 0.025, and Rw = 0.026. Oxidation of Co2+ by diphenyl ditelluride in the presence of “chelating metalloligand” cis-[Mn(CO)4-(TePh)2], followed by carbonyl shift from Mn to Co and a benzenetellurolate group rearranging to bridge two metals, led directly to (CO)3Mn(μ-TePh)3Co(CO)(μ-TePh)2Mn(CO)4. Crystal data: triclinic space group P1, a = 11.689(4) Å,b= 12.509(5) Å, c = 15.930(9) Å, α = 82.85(5)°, β = 74.87(5)°, γ = 70.56(4)°, V= 2119(2) Å3, Z = 2, R = 0.074, and Rw = 0.091. Addition of [Ph3C][BF4] to [(CO)3Mn(μ-TePh)3Mn(CO)3− resulted in formation of the well-known (CO)4Mn(μ-TePh)2Mn(CO)4 dimer. This complex crystallized in the monoclinic space group P21/n with a = 18.852(4) Å,b = 7.094(4) Å, c = 18.604(6) Å, β = 106.29(2)°, V = 2388(2) Å3, Z = 4, final R = 0.048, and Rw = 0.047.
