Glucose-appended photocytotoxic iron(III) complexes of a tridentate Schiff base phenolate ligand [Fe(bpyag)(L)](NO₃) (1–3), where bpyag is N,N-bis(2-pyridylmethyl)-2-aminoethyl-β-d-glucopyranoside and H₂L is 3-(2-hydroxyphenylimino)-1-phenylbutan-1-one (H₂phap) in 1, 3-(2-hydroxyphenylimino)-9-anthrylbutan-1-one (H₂anap) in 2, and 3-(2-hydroxyphenylimino)-1-pyrenylbutan-1-one (H₂pyap) in 3, were synthesized and characterized. The complex [Fe(dpma)(anap)](NO₃) (4), having bis-(2-pyridylmethyl)benzylamine (dpma), in which the glucose moiety of bpyag is substituted by a phenyl group, was used as a control, and the complex [Fe(dpma)(anap)](PF₆) (4a) was structurally characterized by X-ray crystallography. The structure shows a FeN₄O₂ core in a distorted octahedral geometry. The high-spin iron(III) complexes with magnetic moment value of ∼5.9 μ_B showed a low-energy phenolate-to-Fe(III …
