Sonia Torrico-Vallejos,Mauricio F. Erben,Oscar E. Piro,Eduardo E. Castellano,Carlos O. Della Védova,Carlos O. Della Védova +5 more
TL;DR: In this paper, structural and conformational properties of 1H-Isoindole-1,3(2H)-dione, 2-[methoxycarbonyl)thio] (S -phthalimido O -methyl thiocarbonate) are analyzed using a combined approach including X-ray diffraction, vibrational spectra and theoretical calculation methods.
Journal ArticleDOI
Ethyl p-tert-butylcalix(4)arene ethanoate: The role of acetonitrile in the extraction of alkali-metal picrates and on the X-ray structures of the sodium complexes
Angela F. Danil de Namor,Maria A. Pugliese,Alberto R. Casal,Walther B. Aparicio-Aragon,Oscar E. Piro,Eduardo E. Castellano +5 more
TL;DR: In this paper, the X-ray structures of two sodium complexes (picrate as the counter-ion), isolated from water saturated chloroform with and without acetonitrile are reported for the first time.
Journal ArticleDOI
Crystal structure and spectroscopic behavior of three new tris-oxalatoferrate(III) salts
Oscar E. Piro,Gustavo A. Echeverría,Roberto C. Mercader,Ana C. González-Baró,Enrique J. Baran +4 more
TL;DR: In this article, a new general synthetic procedure for preparation of Na3[Fe(C2O4)3]·5H2O (1), Rb3[ Fe(C 2O4]·3H 2O (2), and Cs3[F2O 4]·2H 2 O (3) was developed.
Journal ArticleDOI
Structures of the potassium nitroprusside 2•5 and 0•8 hydrates
TL;DR: Amalvy, Varetti, Aymonino, Castellano, Piro & Punte as mentioned in this paper used the heavy-atom technique and refined anisotropicically to R factors 0.040 and 0.059, from 2805 and 3436 I > 30(/) independent reflections, respectively.
Journal ArticleDOI
On the importance of intermolecular interactions of 3-(2,3-dihydroxy-isopentyl)-4-hydroxyacetophenone: Crystal structure, spectroscopic and hirshfeld surface analysis
Diego M. Gil,Emilio Fernando Lizarraga,Gustavo A. Echeverría,Oscar E. Piro,César A.N. Catalán +4 more
TL;DR: In this paper, the 3-(2,3-dihydroxy-isopentyl)-4-hydroxyacetophenone was synthesized and characterized by 1H Nuclear Magnetic Resonance (NMR), Infrared (IR) and Raman spectroscopies and its crystal structure was solved by single crystal X-ray diffraction.
