Magnetic properties of a cobalt(II) dimer of pseudo tetrahedral geometry [Co-2{(CO)(9)Co3C-COO}(5), C14H19N2H]
(ELSEVIER SCIENCE SA, 2000-12-15)
The crystalline ion pair [Co-2{OOC-CCo3(CO)(9)}(5), C10H6(N(CH3)(2))(2)H] (1) presents unusual magnetic properties. The X-band EPR spectrum of 1 at room temperature presents two unresolved bands at g = 1.98 and 4.55. At a ...
A Co36 cluster assembled from the reaction of cobalt pivalate with 2,3-dicarboxypyrazine
(Wiley VCH Verlag, 2009-11)
A record Co36 cluster is prepared. This mixed-valent compound containing CoII and CoIII centers is formed in the reaction of a dinuclear cobalt pivalate species with the polydentate 2,3-dicarboxypyrazine ligand. In terms ...
Effective Anisotropic Interactions in Spin Pairs Containing High-Spin Ions with Large Zero-Field Splitting
(American Chemical Society, 2018-01)
Analytic and numeric derivations are made of the effective exchange and dipolar magnetic interactions between spin pairs containing S = 3/2 ions, such as high-spin Co(II), S = 5/2 ions, such as high-spin Fe(III) ions, ...
Propiedades electrónicas e interacciones magnéticas en sistemas modelo de metaloproteínas

En este trabajo de tesis estudiamos las propiedades espectroscópicas y magnéticas de cuatro compuestos con metales de transición paramagnéticos: [Cu(II)(tda)(phen)]2 . H2tda (tda = tiodiacetato, phen = 1,10-fenantrolina) ...
Role of imidazole co–ligand in the supramolecular network of a Co(II) complex with sulfadiazine: crystal structure, hirshfeld surface analysis and energetic calculations
(Wiley Blackwell Publishing, Inc, 2020-06)
M(II) complexes with sulfadiazine (SDZ) and imidazole (Im) acting as co-ligand, [M(SDZ)2(Im)2] (M=Co, Ni, Cu and Zn), have been synthesized and characterized. The crystal structure of Co(II) complex (1) is reported, and a ...
Síntesis y caracterización de complejos de coordinación con centro metálico de Cu(II) y ligandos derivados de 3,5-dimetilpirazol y ácido 3,5-dinitrobenzóico
(Universidad de los AndesMaestría en QuímicaFacultad de CienciasDepartamento de Química, 2022-07-25)
Durante el paso del tiempo, la automedicación y un incorrecto tratamiento en los residuos de medicamentos, entre otras causas, han llevado a un incremento exponencial en la resistencia de ciertas cepas de microorganismos ...
