Monomeric and Bridged (2,3,9,10-Tetramethyl-1,4,8,11-tetraaza-1,3,8,10-cyclotetradecatetraen)iron(II) Complexes with Diaxial LigandsThe reaction of [FeTIM(CH3CN)2](PF6)2 (5) with mono- and bidentate ligands L, e. g. pyridine (py), substituted pyridines, 4,4′-bipyridine (bpy), 1,4-diisocyanobenzene (dib), pyrazine (pyz), 4-cyanopyridine (4-pyCN), imidazole (imH), 1,2,4-triazole (triH), yields the iron(II) complexes of 2,3,9,10-tetramethyl-1,4,8,11-tetraaza-1,3,8,10-cyclotetradecatetraene (TIM) [FeTIM(L)2](PF6)2 (6a-u). The bridged complexes 8a-e (e. g. [FeTIM(μ-pyz)- (H2O)]n(PF6)2n (8a)) were obtained with the ligands pyz, bpy, dib, 4-pyCN and 4-isocyanopyridine (pyNC). Similarly, with L = imH, triH, and tetrazole (tetH), the bridged complexes 10a-c, e. g. [FeTIM(μ-im)]n(PF6)n (10a), were formed.
Notes:
Durch Umsetzung von [FeTIM(CH3CN)2](PF6)2 (5) mit ein- und zweizähnigen Liganden L, z. B. Pyridin (py), substituierte Pyridine, 4,4′-Bipyridin (bpy), 1,4-Diisocyanbenzol (dib), Pyrazin (pyz), 4-Cyanpyridin (4-pyCN), Imidazol (imH), 1,2,4-Triazol (triH), wurden die monomeren Eisen(II)-Komplexe von 2,3,9,10-Tetramethyl-1,4,8,11-tetraaza-1,3,8,10-cyclotetradecatetraen (TIM) [FeTIM(L)2](PF6)2 (6a-u) erhalten. Mit den Liganden pyz, bpy, dib, 4-pyCN, 4-Isocyanpyridin (pyNC) konnten auch die verbrückten Komplexe 8a-e (z. B. [FeTIM(μ-pyz)- (H2O)]n(PF6)2n (8a)) gewonnen werden. Mit L = imH, triH und Tetrazol (tetH) wurden die verbrückten Verbindungen 10a-c, z. B. [FeTIM(μ-im)]n(PF6)n (10a) erhalten.
