Abstract

Oxidation of Co²⁺ by diphenyl diselenide in the presence of cis-[PPN][Mn(CO)₄(SePh)₂], followed by carbonyl shift from Mn(I) to Co(III) and a benzeneselenolate group rearranging to bridge two metals, led directly to the thermally unstable (CO)₄Mn(μ-SePh)₂Co(CO)(μ-SePh) ₃Mn(CO)₃. Dropwise addition of [PPN][SePh] to the neutral (CO)₄Mn(μ-SePh)₂Co(CO)(μ-SePh) ₃Mn(CO)₃ resulted in formation of a linear trinuclear complex possessing a hexaselenolatecobalt(III) core, [PPN][(CO)₃Mn(μ-SePh)₃Co(μ-SePh) ₃Mn(CO)₃]. This complex crystallized in the triclinic space group P1̄ with a = 10.878(1) Å = 15.095(2) Å, c = 25.372(4) Å, α = 95.04(1)°, β= 95.00(1)°, γ = 91.52(2)°, V = 4132(2) Å³, and Z = 2; final R = 0.042 and R_w = 0.042. In contrast, the thermally unstable da-[PPN][Mn(CO)₄(SeMe)₂], which was reacted with Co(C10₄)₂·6H₂O and (MeSe)₂ in THF under a nitrogen atmosphere, led to the isolation of the stable heterometallic selenolate (CO)₄Mn(μ-SeMe)₂Co(CO)(μ-SeMe) ₃Mn(CO)₃. Crystal data: monoclinic space group C2/c, a = 28.41.3(7) Å, b = 11.091(3) Å, c = 22.849(6) Å, β= 125.06(3)°, V = 5894(3) Å³, and Z = 8; final R = 0.047 and R_w = 0.048. The results indicated that the distinct electronic effects between methaneselenolate and benzeneselenolate play a key role in stabilizing the neutral Mn(I)-Co(III)-Mn(I)-selenolate complexes.
