Résumé en anglais
In this work, we have re-examined the photomagnetic properties of a series of binuclear iron(II) complexes of formula [{Fe(L)(NCX)2}2bpym], where L is bpym = 2,2-bipyrimidine and bt = 2,2-bithiazoline and X = S, Se, by ...Lire la suite >
In this work, we have re-examined the photomagnetic properties of a series of binuclear iron(II) complexes of formula [{Fe(L)(NCX)2}2bpym], where L is bpym = 2,2-bipyrimidine and bt = 2,2-bithiazoline and X = S, Se, by light irradiation at 647.1–676.4 nm and at 830 nm and we confirm that after optical excitation the magnetic behaviors of [{Fe(bpym)(NCSe)2}2bpym](2), [{Fe(bt)(NCS)2}2bpym](3) and [{Fe(bt)(NCSe)2}2bpym](4) are close to the antiferromagnetic response of [{Fe(bpym)(NCS)2}2bpym](1) characterized by two iron(II) metal ions in the HS electronic configuration...< Réduire
