AbstractA series of cobalt(II) complexes of a highly electron-withdrawing amido ligand, [N(C6F5)(C6H3Pr2i-2,6)](-)(L), were synthesized and structurally characterized. Mononuclear [CoL(Cl)(TMEDA)] (3) and heterobimetallic [CoL2(mu-Cl) Li(THF)(3)] (4) were obtained by direct metathetical reactions of anhydrous CoCl2 with one molar equivalent of [LiL(TMEDA)] (1) (TMEDA = Me2NCH2CH2NMe2) and [LiL(THF)(3)] (2), respectively. Complex 3 underwent facile ligand substitution reactions with LiMe and NaN3, yielding the corresponding mixed-ligand complexes [CoL(X)(TMEDA)] (X = Me 5, N(3)6). Treatment of 3 with NaOMe led to the heterobimetallic complex [CoL2(mu-OMe)Na(TMEDA)] (7). The solid-state structures of complexes 1-7 were established by X-ray diffraction analysis.
