Synthesis and characterization of new mixed-valent Mn(II)/Mn(III) and mixed metal Ni/Mn complexes Ledezma Gairaud, Marisol Pineda, L.W. Aromí Bedmar, Guillem Sañudo Zotes, Eva Carolina Lligands Propietats magnètiques Ligands Magnetic properties Microwave assisted synthesis and bench-top reactions are compared for Mn and Mn/Ni reaction systems with substituted salicylic acid (2-hydroxy-6-isopropyl-3-methylbenzoic-acid (SALOH2). When Mn salts are used, the microwave assisted synthesis and the bench-top reaction afford the same product: the new octanuclear Mn(II)/Mn(III) complex [Mn8O2(OMe)2Cl2(SALO)6(MeOH)4(H2O)2] (1). However, in a mixed metal Mn/Ni reaction the bench-top reaction results in the new heterometallic distorted cubane complexes [Pr2NH2][Mn2Ni2(OH)2(L1)2(SALO)2(SALOH)3] (where L1H = 3-dimethylamino-1-propanol), (2) and [Pr2NH2][Mn2Ni2(OH)(OMe)2(L1)(MeCN)(SALO)2(SALOH)3] (3). The crystal structure and magnetic properties of the prepared complexes are presented. 2020-03-30T10:15:14Z 2020-03-30T10:15:14Z 2015-06-09 2020-03-30T10:15:14Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: https://doi.org/10.1016/j.ica.2015.05.030 Inorganica Chimica Acta, 2015, vol. 434, p. 215-220 https://doi.org/10.1016/j.ica.2015.05.030 cc-by (c) Mognon, Lorenzo et al. http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/openAccess Elsevier B.V.
