New lower rim calix(4)arene derivatives with mixed pendent arms and their complexation properties for alkali-metal cations. Structural, electrochemical, and thermodynamic characterization
TL;DR: In this paper, the synthesis and characterization of two lower rim calix derivatives containing mixed pendent arms was described. The derivatives are 5,11,17,23,23-tetrakis(1,1-dimethylethyl)-25,27-bis[2-(methylthio)etho...
Journal ArticleDOI
Structural and Spectroscopic Characterization of Two New Thallium(I)/Thiosaccharinate Complexes
TL;DR: In this paper, the crystal structures of two Thallium(I)-Thiosaccharinat-Komplexes have been determined at 116 K by single crystal X-ray diffractometry.
Journal ArticleDOI
The addition reaction of diamides to 1,2,5‐thiadiazole 1,1‐dioxide derivatives
José Alberto Caram,María Virginia Mirífico,S.L. Aimone,Oscar E. Piro,Eduardo E. Castellano,Enrique Julio Vasini +5 more
TL;DR: In this paper, the reactions of several derivatives of 1,2,5-thiadiazole 1,1-dioxide were followed by cyclic voltammetry (CV) and UV-visible spectrophotometry in aprotic solvent solution.
Journal ArticleDOI
New Rhenium(V) Nitrofuryl Semicarbazone Complexes.Crystal Structure of [ReOCl2(PPh3)(3-(5-Nitrofuryl)acroleine semicarbazone)]
Lucía Otero,Pabla Noblía,Dinorah Gambino,Hugo Cerecetto,Mercedes González,Roberto A. Sánchez-Delgado,Eduardo E. Castellano,Oscar E. Piro +7 more
TL;DR: In this article, the synthesis and characterization of the first Re complexes with semicarbazone ligands is presented. But the Re(V) ion is in a distorted octahedral environment, equatorially coordinated to a deprotonated semicarazone molecule acting as a bidentate ligand through its carbonylic oxygen and azomethynic nitrogen atoms, to an oxo ligand and a chlorine atom.
Journal ArticleDOI
Intermolecular interactions in antipyrine-like derivatives 2-halo-N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)benzamides: X-ray structure, Hirshfeld surface analysis and DFT calculations
