Solution and solid state properties of Fe(III) complexes bearing N-ethyl-N-(2-a...
Martinho, Paulo N.; Vicente, Ana I.; Realista, Sara; Saraiva, Marta S.; Melato, Ana I.; Brandão, Paula; Ferreira, Liliana P.; Carvalho, Maria de DeusThe effect of the phenolate ring derivatisation on the magnetic properties of Fe(III) complexes bearing N-ethyl-N-(2-aminoethyl)salicylaldiminate ligands both in solid state and solution have been investigated. Two new complexes [Fe(3,5-Br-salEen)2]ClO4.EtOH (5) and [Fe(3,5-Br-salEen)2]BPh4.DMF (6) have been synthesised. SQUID magnetometry studies on these complexes showed that while complex 5 is in the low-spi...
Synthesis and catalytic properties of manganese(II) and oxovanadium(IV) complex...
Fernandes, Tiago A.; Nunes, Carla D.; Vaz, Pedro D.; Calhorda, Maria José; Brandão, Paula; Rocha, João; Gonçalves, Isabel S.; Valente, Anabela A.Reaction of [MnIII(acac)3] and [VIVO(acac)2] with the 1,4-diazabutadiene (DAB) ligands Ph-DAB-(CH2)3R [R = Si(OEt)3(1a); H (1b)] (L) leads to complexes of the type [MnII(acac)2L] and [VIVO(acac)L]Cl in good yields. These complexes were characterised by spectroscopic techniques, and magnetic measurements showed that in the case of the manganese the metal was reduced during the reaction with the nitrogen ligand. ...
