Abstract
The U(III) mixed-sandwich compound [U(η-Cp*)(η-C8H4{SiiPr3-1,4}2)] 1 may be prepared by sequential reaction of UI3 with KCp* followed by K2[C8H4{SiiPr3-1,4}2], and has been crystallographically characterized. 1 reacts reversibly with dinitrogen to afford dimeric [{U(η-Cp*)(η-C8H4{SiiPr3-1,4}2)}2(μ-η2:η2-N2)] 2 , whose X-ray crystal structure reveals a sideways-bound, bridging diazenido (N22-) ligand.Keywords
