Structure, magnetism and catecholase activity of the first dicopper(ii) complex having a single μ-alkoxo bridge

Abstract

Pyridine-2,6-dimethanol shows a neutral, monoanionic and dianionic coordination behaviour with two different coordination modes viz. tridentate and bidentate towards Cu(ii), leading to three different geometric environments around Cu(ii) centers.

Cu(ii) complex of a new isoindole derivative: structure, catecholase like activity, antimicrobial properties and bio-molecular interactions

“…The value of k cat , 1.04 Â 10 4 is comparable to the reported values. [30][31][32] The ESI-MS mass spectrum of the mixture of Cu(II) complex and DTBC (1 : 100, mole ratio) throws some light on the probable mechanism of the catalytic reaction. The mass spectrum (Fig.…”

Facile synthesis of novel NNO-tethered copper(ii) complexes: characterization details, theoretical studies, promising enzyme-like activities, and biomolecular interactions

“…[9][10][11][12][13] One such renowned enzyme is catechol oxidase, a dinuclear Cu(II)-containing enzyme with type-III active sites. [14][15][16][17] It exclusively catalyses the oxygen-mediated oxidation of o-diphenols (catechols) to their quinones with concomitant four-electron reduction of dioxygen to water in each case. [18][19][20][21] Phenoxazinone synthase, 22 which is yet another hexameric copper oxidase, is naturally present in Streptomyces antibioticus bacteria.…”

A new mononuclear Fe(iii) Mannich-base complex with selective histidine binding and catechol oxidase activity

“…16–19 In recent times, the catecholase activity of transition metal complexes with redox active metal ions have been explored for the development of a bioinspired catalyst. 20–27…”

“…[16][17][18][19] In recent times, the catecholase activity of transition metal complexes with redox active metal ions have been explored for the development of a bioinspired catalyst. [20][21][22][23][24][25][26][27] Herein, we report the synthesis, characterization, and bifunctional activity of a Fe(III)-Mannich-based complex 1 [Fe III L(bzac)]. For the synthesis of complex 1, N,N 0 -dimethyl-N,N 0 -bis(2-hydroxy-3,5-dichlorobenzyl)-ethylenediamine (H 2 L) is used.…”
