Oxidative DNA damage induced by S(IV) in the presence of Cu(II) and Cu(I) complexes
(Sociedade Brasileira de Química, 2009)
The DNA damage induced by S(IV) in the presence of some Cu(II) complexes in air saturated solution was investigated. The addition of S(IV) to an air saturated solution containing CuII GGA (GGA = glycylglycyl-L-alanine), ...
Síntese e caracterização de complexos de Cu(I), Cu(II) E Au(I) com ligantes triazenidos contendo substituintes triazóis
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2013-11-29)
Triazenido ions are isoelectronic to amidinato anions,[R'N C(R)=NR']- and have a broad versatility in coordination chemistry. Metal complexes including triazenido ligands find applications in various areas of chemistry. ...
Infrared spectrum of the bis-(1,10-phenanthroline) Cu(I) and Cu(II) perchlorate complexes
(Elsevier, 1996)
FT-IR spectra of the title compounds and derivatives were measured in the range 4000-120 cm-1. A complete experimental spectral assignment has been performed. A simplified normal coordinate treatment orientates some ...
Synthesis, characterization and activity of imidazolate-bridged and Schiff-base dinuclear complexes as models of Cu,Zn-SOD. A comparative study
(Elsevier Science Inc, 2016-10)
Two imidazolate-bridged diCuII and CuIIZnII complexes, [CuZn(dien)2(μ-Im)](ClO4)3·MeOH (1) and [Cu2(dien)2(μ-Im)](ClO4)3 (2) (Im = imidazole, dien = diethylenetriamine), and two complexes formed with Schiff base ligands, ...
Mono-, bis- e tris-triazenos, tetrazeno e complexos de Cu(I), Ag(I), Au(I), Cu(II), Ni(II), Pd(II) E Cu(III): síntese, caracterização, estrutura cristalina, atividades antitumoral, antibacteriana e de clivagem do DNA in vitro
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2013-01-31)
Multi-nitrogenated ligands are versatile coordinating ligands to the transition metals. In this
work, mono- and bis-triazenes, a tris-triazene, a tetrazenide and twelve metal complexes were
synthesized, including the ...
Reactivity of towards copper (I) compounds: Synthesis of binuclear heteromettalic species having CS2 bridging Fe(O) and Cu(I)Reatividade do [Fe(CO)2(2-CS2)(PPh3)2] frente a compostos de Cu(I): Síntese de espécies binucleares heterometálicas contendo CS2 em ponte entre Fe(0) e Cu(I).
(2007-01-01)
This work describes the one pot syntheses and characterization of two new heterometallic carbonyl compounds of the type [Fe(CO)3(m-CS2)(PPh3)(CuX)], X = Cl, ClO4. Both compounds were investigated by infrared and 31P{1H} ...
Four novel mononuclear and polynuclear Cu(I) thiosaccharinates with triphenylphosphane and bis(diphenylposphino)methane. Synthesis and structural study of Cu(4)(tsac)(4)(PPh(3))(3), Cu(tsac)(PPh(3))(2), Cu(4)(tsac)(4)(dppm)(2), and Cu(2)(tsac)(2)(dppm)(2)
(ELSEVIER SCIENCE SA, 2009)
Four new ternary complexes of copper(I) with thiosaccharin and phosphanes were prepared. The reaction of [Cu(4)(tsac)(4)(CH(3)CN)(2)] (1) (tsac: thiosaccharinate anion) with PPh(3) in molar ratios Cu(I)/PPh(3) 1:075 and ...
Experimental evidence of the disproportionation equilibrium in copper mixed-valence complexes
(2000)
Experimental evidence for a dismutation equilibrium in the mixed-valence (MV) [Mn+ -M(n+1)+] system type has been elusive and its existence can be established only when the oxidation-reduction processes involved are ...
