Journal ArticleDOI
The role of non-covalent interactions in some 2-trifluoromethylchromones in the solid state
Christian David Alcívar León,G.A. Echeverría,Oscar E. Piro,S.E. Ulic,S.E. Ulic,Jorge L. Jios,Jaime Andrés Pereañez,Isabel C. Henao Castañeda,Hiram Pérez +8 more
TL;DR: In this paper, the intermolecular interactions in the solid state and the spectroscopic vibrational, electronic and NMR properties of new 3-methyl-substituted-2-trifluoromethylchromone derivatives with NH2 groups were discussed with the assistance of DFT calculations.
Journal ArticleDOI
On a Novel Synthesis of 2-Sulfonatobenzoic Acid by Oxidation of Thiosalicylic Acid Catalyzed by Copper(II): a Structural Study
TL;DR: In this paper, the structure of the tetraphenylphosphonium 2-sulfonatobenzoic acid has been determined by X-ray diffraction methods.
Journal ArticleDOI
Reversible S-S Bond Breaking and Bond Formation in Disulfide-Containing Dinuclear Complexes of MnI.
TL;DR: The chemistry of this disulfide derivative is explored with regard to the controlled scission and formation of the sulfurÿsulfur bond, promoted either by redox processes or by combined redox and acid-base treatments.
Journal ArticleDOI

Ana C. González-Baró,Oscar E. Piro,Beatriz S. Parajón-Costa,Enrique J. Baran,Eduardo E. Castellano +4 more
TL;DR: In this paper, a triclinic space group P1 (a=9.413, b=10.595, c=11.783, α=103.59, β=101.98, γ=99.40, Z=2) was characterized by spectroscopic and X-ray crystallographic methods.
Journal ArticleDOI
Structural, spectroscopic and theoretical studies on dixanthogens: (ROC(S)S)2, with R = n-propyl and isopropyl
TL;DR: In this paper, the structural and conformational properties of two dixanthogen molecules, [CH3(CH2)2OC(S)S]2 and [(CH3)2CHOCS) S]2, were analyzed using a combined experimental and theoretical approach, with data obtained from structural X-ray diffraction methods, IR, Raman and UV-visible spectroscopies, and DFT calculations.
