| Abstract: | Syntheses and Crystal Structures of new Amido- und Imidobridged Cobalt Clusters: Li(THF)2]3Co3(μ2-NHMes)3Cl6] (1), Li(DME)3]2Co18(μ4-NPh)3(μ3-NPh)12Cl3] (2), Li(DME)3]2Co6(μ4-NPh)(μ2-NPh)6(PPh2Et)2] (3), and Li(THF)4]Co8(μ3-NPh)6(μ2-NPh)3(PPh3)2] (4) The reactions of cobalt(II)-chloride with the lithium-amides LiNHMes and Li2NPh leads to an amido-bridged multinuclear complex Li(THF)2]3Co3(μ2-NHMes)3Cl6] ( 1 ) as well as to the imido-bridged cobalt cluster Li(DME)3]2Co18(μ4-NPh)3(μ3-NPh)12Cl3] ( 2 ). In the presence of tertiary phosphines two imido-bridged cobalt clusters Li(DME)3]2Co6(μ4-NPh)(μ2-NPh)6(PPh2Et)2] ( 3 ) and Li(THF)4]Co8(μ3-NPh)6(μ2-NPh)3(PPh3)2] ( 4 ) result. The structures of 1 – 4 were characterized by X-ray single crystal structure analysis. |
