Polypyridyl iron(iii) complexes containing long alkyl chains: synthesis, characterization, DFT calculations and biological activity

Abstract

A polypyridyl ligand functionalized with a long alkyl chain (LC10) was prepared. Reaction of LC10 with selected iron salts of different stoichiometries formed two metal complexes: [Fe(LC10)(Cl)3] (1) and [Fe(LC10)2](ClO4)3...

Enhancing the biological properties of zinc complexes with bis(indolyl)methane groups: Synthesis, characterization, DNA interaction, and biocide activity

“…The broad absorption at 1095 cm − 1 in 2 strongly suggests the presence of the perchlorate counterion. A similar IR profile was observed in the literature [72]. All the vibrational modes in IR for both complexes agreed with those calculated via density functional theory (DFT), as shown in Fig.…”

Phosphate Triester Hydrolysis by Mononuclear Iron(III) Complexes: The Role of Benzimidazole in the Second Coordination Sphere

“…For 3 , the most intense peak at m/z 578.41 (100 %) related to the ligand without the iron center, but another fragment in m/z 316.21 (20 %) has chemical arrangement [C 36 H 46 FeN 7 O] 2+ , which is concordant with [Fe III (L 3 )] 2+ . A peak corresponding to 2 or 3 structures was not observed, probably due to the reduction of iron(III) to iron(II) which is more labile in solution, during analysis, resulting in ligand dissociation [51] …”

“…A peak corresponding to 2 or 3 structures was not observed, probably due to the reduction of iron(III) to iron(II) which is more labile in solution, during analysis, resulting in ligand dissociation. [51] 57 Fe Mossbauer Spectroscopy 57 Fe Mossbauer spectroscopy is a powerful technique to determine the electronic and magnetic state of the Fe centers in complexes. [52] In addition, very small impure phases (with Fe) can also be observed through this technique, thus giving us information about the purity of the sample.…”
