Investigation of easy-plane magnetic anisotropy in P-ligand square-pyramidal Co-II single ion magnets Mondal, Amit Kumar Jover Modrego, Jesús Ruiz Sabín, Eliseo Konar, Sanjit Imants Lligands Complexos metàl·lics Magnets Ligands Metal complexes In this work we report two pentacoordinated Co-II-P4X1 Single Ion Magnets (SIMs) based on P-donor ligands. The tetradentate ligand tris[2-(diphenylphosphino) ethyl] phosphine allows the obtention of the isostructural square pyramidal [Co(PP3)Cl]center dot ClO4 (1) and [Co(PP3)Br]center dot ClO4 (2) complexes. Consistent theoretical and experimental studies indicate that these complexes have a high spin (S = 3/2) ground state and suggest that the relaxation dynamics is governed by ground state quantum tunneling, whereas its temperature dependence is directed by optical or acoustic Raman processes. 2019-10-22T07:12:39Z 2019-10-22T07:12:39Z 2017-05-11 2019-10-22T07:12:40Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: https://doi.org/10.1039/c7cc02584j Chemical Communications, 2017, vol. 53, num. 38, p. 5338-5341 https://doi.org/10.1039/c7cc02584j (c) Mondal, Amit Kumar et al., 2017 info:eu-repo/semantics/openAccess Royal Society of Chemistry Articles publicats en revistes (Química Inorgànica i Orgànica)
