Effect of non-covalent self-dimerization on the spectroscopic and electrochemical properties of mixed Cu(i) complexes

Abstract

Organized crystal packing from non-covalent dimers and the self-dimerization in solution of Cu(NN′)(PPh3)Br] were characterized. Differences in Cu(ii)/Cu(i) potentials between the monomer and dimer are modulated by the non-covalent interactions.

Oral administration of a new copper (I) complex with coumarin as ligand: modulation of the immune response and the composition of the intestinal microbiota in Onchorhynchus mykiss

“…The synthesis of Cu(I) coordination compound [Cu(NN 1 ) 2 ]ClO 4 , where NN 1 is the ligand 6-((quinolin-2-ylmethylene)amino)-2H-chromen-2-one was carried out by template condensation method ( Cáceres-Vásquez et al, 2023 ). To 3 mmol of the precursor reagent [Cu(CH 3 CN) 4 ]ClO 4 dissolved in 50 mL of acetonitrile, double of the amounts of the reactants 2-quinoline-carboxaldehyde (6 mmol) and 6-amino-chromen-2-one (6 mmol), dissolved in acetonitrile, were added and maintained at room temperature and constant stirring for 1 h, forming a colored solution.…”

“…The adaptability of transition metal compounds, in particular Cu(I) coordination complexes with bidentate nitrogen donor ligands, is well known. Therefore, several researches have been conducted towards the controlled obtaining of its electrochemical properties through the selection of its ligands ( Cáceres-Vásquez et al, 2023 ). For all the aforementioned problems and considering the need to generate alternatives to antibiotics, in addition to the positive effect that natural compounds and their derivatives have, added to the properties that transition metal complexes possess, our research group has synthesized a new [Cu(NN 1 ) 2 ]ClO 4 complex, where NN 1 is a 6-((quinolin-2-ylmethylene)amine)-2H imine ligand-chrome-2-one, a derivative of the natural compound coumarin ( Aldabaldetrecu et al, 2020 ).…”

[Cu(NN1)2]ClO4, a Copper (I) Complex as an Antimicrobial Agent for the Treatment of Piscirickettsiosis in Atlantic Salmon

“…The synthesis of Cu(I) coordination compound [Cu(NN 1 ) 2 ]ClO 4 , where NN 1 is the ligand 6-((quinolin-2-ylmethylene)amino)-2H-chromen-2-one was carried out using the template condensation method [30]. To 3 mmol of the precursor reagent [Cu(CH 3 CN) 4 ]ClO 4 dissolved in 50 mL of acetonitrile, double the amounts of the reactants 2-quinolinecarboxaldehyde (6 mmol) and 6-amino-chromen-2-one (6 mmol), dissolved in acetonitrile, were added and maintained at room temperature and constant stirring for 1 h, forming a colored solution.…”

“…The adaptability of transition metal compounds, in particular, Cu(I) coordination complexes with bidentate nitrogen donor ligands, is well known. Therefore, several studies have been conducted towards the controlled obtaining of its electrochemical properties through the selection of its ligands [30]. Considering the need to use alternatives to antibiotics, in addition to the positive effects of natural compounds and their derivatives, added to the properties that transition metal complexes possess, our working group has synthesized a new [Cu(NN 1 ) 2 ]ClO 4 complex, where NN 1 is a 6-((quinolin-2-ylmethylene)amine)-2H imine ligand-chrome-2-one, a derivative of the natural compound coumarin.…”
