A remoção de Cu (10 mg L) complexado por ácido húmico comercial (100 mg L) foi estudada a diferentes densidades de corrente (30-80 mA cm) usando uma célula filtro-prensa, ânodo de Ti/Ru 0.3 Ti 0.7 O 2 e cátodo de aço inoxidável. As eletrólises foram feitas com e sem membrana separando os compartimentos da célula [aniônica homogênea (Nafion R117), catiônica heterogênea (Ionac MC-3470) e aniônica...

Molecular docking process was performed to investigate the interactions between synthesized compounds and human epidermal growth factor protein kinase domain EGFR (PDB ID:1M17) cyclin-dependent kinase-2 CDK2 ID:3IG7) proteins. HOMO LUMO orbital energy analysis, quantum chemical calculations were made bioactivity parameters of evaluated. NiII CuII complexes L1H2 L2H2 L3H2, ligands showed higher ...

Two new copper(II) complexes, [Cu2(3-bpfp)(2,6-PDA)2(H2O)2] (1) and [Cu(4-bpfp)0.5 (glu)]·H2O (2), have been hydrothermally synthesized by self-assembly of isomeric bis(pyridylformyl)piperazine ligands [3-bpfp = bis(3-pyridylformyl)piperazine, 4-bpfp = bis(4pyridylformyl)piperazine], rigid pyridine-2,6-dicarboxylic acid (2,6-H2PDA) or flexible glutaric acid (H2glu), and copper(II) chloride. Sin...

It is demonstrated here that tridentate imine ligands can control the nuclearity of copper(II) complexes based on the donor atoms present in the ligand. The N,N',N''-donating imine ligand led to a mononuclear compound, namely di-chlorido-[N,N-dimethyl-N'-(pyridin-2-yl-methyl-idene)ethane-1,2-di-amine]copper(II) monohydrate, [CuCl2(C10H15N3)]·H2O, 1, while the N,N',O-donating imine ligand produc...

In the title dinuclear complex, (acetonitrile-1κN)[μ-N-(pyri-din-2-ylcarbonyl)pyridine-2-carboxamidato-1:2κ(5)N,N',N'':O,O'][N-(pyridin-2-ylcarbonyl)pyridine-2-carboxamidato-2κ(3)N,N',N'']bis(trifluoromethanesulfonato-1κO)dicopper(II), [Cu(2)(C(12)H(8)N(3)O(2))(2)(CF(3)O(3)S)(2)(CH(3)CN)], one of the Cu(II) ions is five-coordinated in a distorted square-pyramidal N(3)O(2) environment provided b...
