Journal ArticleDOI
Magnetism and structure in chains of copper dinuclear paddlewheel units.
Mireille Perec,Ricardo Baggio,Rosana P. Sartoris,Ricardo Costa de Santana,Octavio Peña,Rafael Calvo +5 more
TL;DR: An anhydrous copper carboxylate compound of formula [Cu(trans-2-butenoate)(2)](n) has been characterized, and X-ray analysis reveals a structure built by paddlewheel units bridged by pairs of Cu...O axial bonds to give infinite chains arranged in a new topological motif.
Journal ArticleDOI
Collapse of the EPR fine structure of a one-dimensional array of weakly interacting binuclear units: A dimensional quantum phase transition
TL;DR: In this article, the role of weak inter-binuclear exchange couplings in Bose-Einstein condensation was investigated using electron paramagnetic resonance (EPR) spectra, elementary excitations, and spin dynamics of a one-dimensional array of antiferromagnetic (AFM) binuclear units.
Journal ArticleDOI
Structure, Single Crystal EPR Spectra, and Exchange Interactions in [Cu(l-proline)2]2·5H2O and Cu(d,l-proline)2·2H2O
Rosana P. Sartoris,L. Ortigoza,Nieves M. C. Casado,Rafael Calvo,Eduardo E. Castellano,Oscar E. Piro +5 more
TL;DR: The data in compound II indicate that a superexchange pathway containing a weak hydrogen bond C-H- - -O is the path for an exchange interaction with |J'/k| = 48 mK between coppers in neighbor layers at 9.75 Å.
Journal ArticleDOI
New copper(II)-radical one dimensional chain: Synthesis, crystal structure, EPR, magnetic properties and DFT calculations.
Denise A. Souza,Antonio S. Florencio,Stéphane Soriano,Rafael Calvo,Rosana P. Sartoris,José Walkimar de M. Carneiro,Claudio Sangregorio,Claudio Sangregorio,Miguel A. Novak,Maria G. F. Vaz +9 more
TL;DR: Comparison of this compound with other Cu-NIT radicals chains bearing different substituents in the organic radicals, highlights that the beta-diketonate ligand plays an important role in determining the final architecture.
Journal ArticleDOI
1-D polymers with alternate Cu2 and Ln2 units (Ln = Gd, Er, Y) and carboxylate linkages.
Rafael Calvo,R. E. Rapp,Edson F. Chagas,Rosana P. Sartoris,Ricardo Baggio,María Teresa Garland,Mireille Perec +6 more
TL;DR: Three isostructural Cu 2Ln 2 1-D polymers, synthesized and characterized by X-ray crystallography, electron paramagnetic resonance, and magnetic measurements, indicate bulk antiferromagnetic behavior of the three compounds at low temperatures.
