Popis:	The ion-separated complex 2[Li(thf) 4 ] + [Mn(C 12 H 8 N) 4 ] 2- 1 has been obtained from the nucleophilic substitution reaction of [Mn{N(SiMe 3 ) 2 } 2 ]·2thf with Li[C 12 H 8 N] (1∶4 equivalents) (thf = tetrahydrofuran, C 12 H 8 N = carbazol-9-yl), and the molecular species [Mn(C 12 H 8 N) 2 ]·3thf 2 from the acid–base reaction of [Mn{N(SiMe 3 ) 2 } 2 ]·2thf and C 12 H 8 NH (1∶2 equivalents). They are among the few amidomanganese(II) complexes containing simple (sterically 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.
