摘要：

The complexation of tridentate trianionic chelating ligands, N-(2-hydroxyphenyl)salicylamide (H3L1) and its homologs with a substituent on the 2-hydroxyphenyl moiety (5-CH3, H3L2; 5-Cl, H3L3), toward iron ion has been studied. The ligand H3L1 formed a high-spin iron(III) complex K3[Fe(L1)2] when treated with FeCl3 in an alkaline solution under open atmosphere. This complex was oxidized with Ce(IV) to a high-spin iron(IV) complex (NPr4)2[Fe(L1)2]. The ligand H3L2 formed a low-spin iron(IV) complex K2[Fe(L2)2] under open atmosphere, whereas the ligand H3L3 gave a high-spin iron(III) complex (PBu4)3[Fe(L3)2]. The complexes were characterized by means of cyclic voltammetry, electronic spectra and Mossbauer spectra.
