Transition metal complexes of a versatile polyalkoxy oxazolidine-based ligand derived from in situ cyclizationSaleem, Ayaan, Kobielska, Paulina A., Harms, K., Katsikogianni, Maria G., Telford, Richard, Novitchi, G., Nayak, Sanjit 10 April 2018 (has links)
Yes / One-pot reaction between 8-hydroxyquinoline-2-carboxaldehyde (HQC) and tris(hydroxymethyl)aminomethane (TRIS) followed by in situ cyclization yielded an oxazolidine based ligand which produced four mononuclear complexes of MnII(1), CoII(2), NiII(3), ZnII(4), a tetranuclear iron (FeIII4) complex (5) and a trinuclear cobalt (CoIICoIII2) complex (6). Magnetic studies show dominant antiferromagnetic interaction in tetranuclear iron (FeIII4) complex 5 and presence of the slow relaxation of magnetisation in 6. The compounds were also studied for their antibacterial properties. The oxazolidine ligand (H3L2) of this study showed good antimicrobial activity not only against Gram-positive bacteria but against Gram-negative bacteria too. The antimicrobial efficacy of the metal complexes (1–6) is also reported. / The full-text of this article will be released for public view at the end of the publisher's embargo period on 11 Apr 2019.
