Original language description

The iron(III) salen-type complexes [Fe(salen)(L)](n) (1-6) involving heterocyclic N-donor ligands HL {HL = 1H-imidazole (Himz), 1H-tetrazol-5-amine (Hatz), 5-methyl-1H-tetrazole (Hmtz), 1H-benzimidazole (Hbimz), 1H-1,2,4-triazole (Htriz) and 1H-benzotriazole (Hbtriz)} have been prepared and characterised by elemental analysis, FT IR, CI mass and Fe-57 Mossbauer spectroscopies, and variable temperature magnetic measurements. Single crystal X-ray analysis of [Fe(salen)(btriz)](n) (6) revealed a 1D chain-polymeric structure of the complex with the btriz anion as a bridging ligand. Magnetic data for all complexes were fitted using Fisher's model (for S = 5/2) and also using a heptanuclear closed ring model showing a weak antiferromagnetic interaction (J approximate to -1 to -2 cm(-1)), and moreover, molecule-based magnet properties have been observed in the case of [Fe(salen)(atz)](n) (2). The exponential correlation between the magnetic properties (the isotropic exchange parameter J) and
