New topologies in pentanuclear nickel/oximato clusters: structural and magnetic characterization Esteban Jarne, Jordi Font Bardia, Ma. Mercedes Sánchez Costa, José Teat, Simon J. Escuer Fité, Albert Lligands Propietats magnètiques Teoria quàntica Ligands Magnetic properties Quantum theory In the present work, five new Ni5 clusters employing the versatile 2-pyridylcyanoxime ligand have been synthesized and chemically, structurally, and magnetically characterized. The crystallographic examination of these Ni5 clusters together with those already published in the literature, giving a total number of 14 complexes, exhibiting up to 8 different topologies for which the relationship between topology, reaction conditions and magnetic response has been analyzed. DC magnetic measurements were carried in the 300-2 K range for the new complexes and the analysis of the experimental data revealed an antiferromagnetic response for the oximato mediated interactions with a variety of ground states (S = 0, 1, 3) as function of the cluster topology. 2020-06-12T07:04:03Z 2020-06-12T07:04:03Z 2014 2020-06-12T07:04:03Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 0020-1669 https://hdl.handle.net/2445/165286 634889 eng Versió postprint del document publicat a: https://doi.org/10.1021/ic500057j Inorganic Chemistry, 2014, vol. 53, num. 6, p. 3194-3203 https://doi.org/10.1021/ic500057j (c) American Chemical Society , 2014 info:eu-repo/semantics/openAccess 36 p. application/pdf American Chemical Society Articles publicats en revistes (Mineralogia, Petrologia i Geologia Aplicada)
