Título: | Preparation and properties of a calcium(II)-based molecular chain decorated with manganese(II) butterfly-like complexes |
Autor: | Benniston, Andrew C.; Melnic, S.; Turta, C.; Arauzo, Ana B. CSIC ORCID; Bartolomé, Juan CSIC ORCID; Harrington, R. W.; Probert, M. R. | Fecha de publicación: | 2014 | Editor: | Royal Society of Chemistry (UK) | Citación: | Dalton Transactions 43(35): 13349-13357 (2014) | Resumen: | The room temperature reaction of [Mn2O2(bipy) 4](ClO4)3 (bipy = 2,2′-bipyridine) with Ca(CHCl2COO)2 in methanol produced a yellow crystalline material. The X-ray determined structure comprises of a multiple calcium(ii) carboxylate bridged chain-like structure which is decorated with [Mn(bipy) 2(OH2)]2+ subunits. The redox behaviour for the complex in H2O and MeCN is reported. In the latter solvent the oxidation of the manganese ions appears to be facilitated by the presence of the calcium ions. Magnetic susceptibility and low temperature magnetization measurements show that the Mn moment is isotropic, with g = 1.99(1) and S = 5/2, confirming it is in the 2+ oxidation state. A very weak antiferromagnetic interaction is also detected. Frequency-dependent ac measurements evidence slow magnetic relaxation of the Mn(bipy)2 units. Two relaxation mechanisms are identified: a very slow direct process and a faster one caused by the Resonant Phonon Trapping mechanism. This is the first example of field-induced single ion magnet (SIM) behavior in a mononuclear Mn(ii) complex. © 2014 The Royal Society of Chemistry. | Descripción: | This Open Access Article is licensed under a Creative Commons Attribution 3.0 Unported Licence. | Versión del editor: | http://dx.doi.org/10.1039/C4DT01518E | URI: | http://hdl.handle.net/10261/120918 | DOI: | 10.1039/C4DT01518E | Identificadores: | doi: 10.1039/C4DT01518E e-issn: 1477-9234 issn: 1477-9226 |
