Oxidative addition of diorganyl diselenides to the coordinatively unsaturated, low-valent transition-metal-carbonyl fragment [Mn(CO)5]- produced cis-[Mn(CO)4(SeR)2]-. The complex cis-[PPN][Mn(CO)4(SePh)2] crystallized in triclinic space group P1? with a = 10.892(8) ?, b = 10.992(7) ?, c = 27.021(4) ?, α = 101.93(4)°, β = 89.79(5)°, γ = 116.94(5)°, V = 2807(3) ?3, and Z = 2; final R = 0.085 and Rw = 0.094. Thermolytic transformation of cis-[Mn(CO)4(SeMe)2]- to [(CO)3Mn(μ-SeMe)3Mn(CO)3]- was accomplished in high yield in THF at room temperature. Crystal data for [Na-18-crown-6-ether][(CO)3Mn(μ-SeMe)3Mn(CO) 3]: trigonal space group R3?, a = 13.533(3) ?, c = 32.292(8) ?, V = 5122(2) ?3, Z = 6, R = 0.042, Rw = 0.041. Oxidation of Co2+ to Co3+ by diphenyl diselenide in the presence of chelating metallo ligands cis-[Mn(CO)4(SePh)2]- and cis-[Mn(CO)4(TePh)2]-, followed by a bezenselenolate ligand rearranging to bridge two metals and a labile carbonyl shift from Mn to Co, led directly to [(CO)4Mn(μ-TePh)2Co(CO)(μ-SePh) 3Mn(CO)3]. Crystal data: triclinic space group P1?, a = 11.712(3) ?, b = 12.197(3) ?, c = 15.754(3) ?, α = 83.56(2)°, β = 76.13(2)°, γ = 72.69(2)°, V = 2083.8(7) ?3, Z = 2, R = 0.040, Rw = 0.040. Addition of fac-[Fe(CO)3(SePh)3]- to fac-[Mn(CO)3(CH3CN)3]+ resulted in formation of (CO)3Mn(μ-SePh)3Fe(CO)3. This neutral heterometallic complex crystallized in monoclinic space group P21/n with a = 8.707(2) ?, b = 17.413(4) ?, c = 17.541(4) ?, β = 99.72(2)°, V = 2621(1) ?3, and Z = 4; final R = 0.033 and Rw = 0.030.
