Synthesis and characterization of new mixed-valent Mn(II)/Mn(III) and mixed metal Ni/Mn complexes
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 n...

| Sumario: | 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. |
