dc.description.abstract | Treatment of ortho-dimethylarsinoaniline (NASH₂) with 1.0 equivalents of LiBut or 0.5 equivalents of MgBu₂ in tetrahydrofuran affords the complexes [{Li(NASH)(thf)₂}₂](1) and [Mg(NASH)₂(thf)₁.₅](2)(NASH = NHC₆H₄AsMe₂-2). Both complexes have been characterised spectroscopically. The crystal structure determination of 1 reveals a centrosymmetric dimeric structure with an Li₂N₂ central unit that does not exhibit arsino–lithium donor interactions. Compound 2 reacts with dimethylsilicone grease to yield the unexpected complex [{Mg₂(µ²:ƞ¹-NHC₆H₄AsMe₂)₂(µ³:ƞ³-OSiMe₂NC₆H₄AsMe₂)(thf)}₂](3), via the novel and unprecedented insertion of a dimethylsilanone fragment into an Mg–N bond. Compound 3 is tetranuclear with a 12-membered Mg₄N₆O₂ double stacked cube centre that has Mg atoms residing at alternate corners of each cube. The arsino functionalities of the modified ƞ³-bound ligands co-ordinate to Mg atoms on the vertices. | en |
