FERROMAGNETICALLY COUPLED BINUCLEAR Fe(Ⅲ) COMPLEXES THROUGH ISOPHTHALATO-BRIDGE
摘要:
Four new binuclear Fe(Ⅱ) complexes containing the dianion of isophthalic acid as bridge have been synthesized,namely[Fe2(IPHTA) (L)4] (ClO4)4 [L denotes 2,2'-bipyridyl(bpy);1,10-phenanthroline (phen);4,4'-dimethyl-2,2'-bipyridyl (Me2bpy) and 5-nitro-1,10-phenanthroline (NO2-phen),respectively],where IPHTA represents the isophthalate dianion.The complex[Fe2(IPHTA)(phen)4](ClO4)4 was characterized with variable temperature magnetic susceptibility (4-300K).The exchange integral J was found to be 9.96 cm-1,indicating that weakly ferromagnetic spin-exchange interaction operates between Fe(Ⅱ) and Fe(Ⅱ) ions.
