Abstract

The ion-separated complex 2[Li(thf)₄]⁺[Mn(C₁₂H8N)₄] ^2- 1 has been obtained from the nucleophilic substitution reaction of [Mn{N(SiMe₃)₂}₂]·2thf with Li[C₁₂H₈N] (1:4 equivalents) (thf = tetrahydrofuran, C₁₂H₈N = carbazol-9-yl), and the molecular species [Mn(C₁₂H₈N)₂]·3thf 2 from the acid-base reaction of [Mn{N(SiMe₃)₂}₂]·2thf and C₁₂H₈NH (1:2 equivalents). They are among the few amidomanganese(II) complexes containing simple (stericaliy undemanding) dialkyl- or diaryl-amido groups to be characterised. The crystal structures of both were determined: 1 contains the first tetraamidomanganese(II) dianion and 2 possesses the highest co-ordination number for Mn^II in such a compound.
