Electrochemical studies of a dinuclear copper complex with imidazole derivative ligand H3bphenim

Solvent and pH effects on the redox behavior and catecholase activity of a dicopper complex with distant metal centers

“…In both solvent mixtures kinetic parameters were determined at pH = 7.5, to be able to compare the activity with other catalysts developed by the group [28]. A second pH value was chosen for each solvent system as that which gave the largest increment in activity compared to the activity of the medium without the catalyst, coinciding in MeOH/H 2 O with the value of 7.5.…”

A dicopper complex with distant metal centers. Structure, magnetic properties, electrochemistry and catecholase activity

“…In both solvent mixtures kinetic parameters were determined at pH 7.5, to be able to compare the activity with other catalysts developed by the group [41]. A second pH value was chosen for each solvent system as that which gave the largest increment in activity compared to the activity of the medium without the catalyst.…”

Electrochromism and electrochemical properties of complexes of transition metal ions with benzimidazole-based ligand

“…The Cu(II) / Cu(I) reduction is probably associated with the change of coordination geometry of metal center what leads to disassembling/assembling process, 28 as well as to the formation of a solvated copper(I) species with acetonitrile molecules, since this solvent forms stable Cu(I)-acetonitrile complexes in solution. 29 The presence of solvated copper(I) ions in solution is supported by the broad peaks at about +750 mV, +525 mV and +765 mV for 2, 3 and 4 respectively. 30 Spectral changes observed during reduction of Cu(II) complexes 2-4 are shown in Fig.…”
