摘要：
Four novel iron(III) binuclear complexes have been synthesized and characterized, namely [Fe-2(IPHTA)(L)(4)](ClO4)(4) (L denotes 2,2'-bipyridine (bpy); 1,10-phenanthroline (phen); 4,4'-dimethyl-2,2'-bipyridine (Me(2)bpy) and 5-nitro-1,10-phenanthroline (NO2-phen), where IPHTA is the isophthalate dianion. The magnetic susceptibility of [Fe-2(IPHTA) (phen)(4)]-(CiO(4))(4) was measured in the 4-300 K range and the observed data were successfully simulated by the equation based on the spin Hamiltonian operator, (H) over cap= - 2J (S) over cap(1) . (S) over cap(2), giving the exchange integral J = 9.96 cm(-1). This indicates a weak ferromagnetic spin-exchange interaction between the metal ions.
