Título: | Co II/ZnII-(L-tyrosine) magnetic metal-organic frameworks |
Autor: | Silva, Nuno Joâo O.; Palacio, Fernando CSIC ORCID | Fecha de publicación: | 2012 | Editor: | Wiley-VCH | Citación: | European Journal of Inorganic Chemistry 32: 5259-5268 (2012) | Resumen: | Three chiral coordination polymers assembled from L-tyrosine (L-tyr) and cobalt, cobalt/zinc and zinc salts, with a new three-dimensional (3D) structure and formulated as [M(L-tyr)] n (M = Co, Co/Zn, Zn) have been prepared by mild hydrothermal synthesis. These three compounds are isostructural, crystallize with monoclinic symmetry in the C2 space group and possess four crystallographically unique metal sites in tetrahedral (two) and octahedral (two) coordination environments resulting in two slightly distinct edge-sharing metal dimers with L-tyr linking the metal atoms in pillars. These features result in a dense framework. The study of the magnetic properties of the cobalt-bearing solid reveals a ferromagnetic exchange interaction within the Co 2+ dimers. The racemic compound of dl-tyrosine and cobalt was also synthesized and its structure characterized. The crystal structure of chiral isomorphous metal-organic frameworks, [M(L-tyrosine)]n, (M = Co, Zn, Co/Zn) features tetrahedral and octahedral metal sites, resulting in two slightly different edge-sharing metal dimers, with L-tyrosine linking the metal atoms in pillars and forming a dense framework. In the dimers, a ferromagnetic exchange interaction couples the Co 2+ ions. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
