Journal ArticleDOI
Infrared absorption spectra of electronically excited long-lived metastable states in Na2[Ru(CN)5NO]·2H2O
TL;DR: In this article, it was shown that the frequency downshifts of vibrational modes of the RuNO group are far larger than shifts of CN modes, a fact that indicates that the metastable states involve electronic transitions mainly located at that group.
Journal ArticleDOI
Study of 5-nitroindazoles' anti-Trypanosoma cruzi mode of action: Electrochemical behaviour and ESR spectroscopic studies
Jorge Rodríguez,Alejandra Gerpe,Gabriela Aguirre,Ulrike Kemmerling,Oscar E. Piro,Vicente J. Arán,Juan Diego Maya,Claudio Olea-Azar,Mercedes González,Hugo Cerecetto +9 more
TL;DR: The electrochemical studies showed that the trypanocidal 5-nitroindazole derivatives yielded nitro-anion radical via one-electron process at physiological pH in the parasite according to ESR experiment with the T. cruzi microsomal fraction showing that 5-Nitroindrazole derivatives suffer bio-reduction without reactive oxygen species generation.
Journal ArticleDOI
X-ray diffraction study of copper(I) thiourea complexes formed in sulfate-containing acid solutions
Oscar E. Piro,R. C. V. Piatti,Agustín Eduardo Bolzán,Roberto Carlos Salvarezza,Alejandro Jorge Arvia +4 more
TL;DR: The formation of three different copper(I) thiourea complexes in sulfate-containing acid solutions was observed, and the crystal and molecular structure of a new complex, [Cu(2)(tu)(6)](SO(4)).H(2)O, was determined and the formation and structures of [ Cu(2(tu)(5)]( SO(4).3H( 2)O and[Cu(4)( Tu)(7)](so(4)O
Journal ArticleDOI
Crystal structure and magnetic properties of diaqua (L-aspartato)copper(II)
TL;DR: The title compound, Cu(CO 2 NH 2 CHCH 2 CO 2 )(H 2 O) 2, crystallizes in the space group C2, with a=9.504, b=10.038, c=7.555, β=94.01 o, and Z=4.024 as mentioned in this paper.
Journal ArticleDOI
