摘要：

An oxo-bridged binuclear iron(III) complex, [Fe(phen)(H2O)(3)](2)O center dot 2SO(4), has been synthesized and structurally characterized by elemental analysis (EA), IR, TG-DSC and X-ray. Its crystal structure has been determined by X-ray crystallography. It crystallizes in the orthorhombic system, space group P2(1)2(1)2, with lattice parameters a = 17.650(4), b = 8.5133(17), c = 9.971(2) angstrom; V = 1498.2(5) angstrom(3),rho(calcd) = 1.763 g/cm(3) and Z = 4 for R-1 = 0.0601. The crystal structure indicated that two octahedrally coordinated iron(III) ions bridged with oxygen atoms formed a non-linear complex. The bond angle of Fe-O-Fe is 163.9(4)degrees. The data of EA and IR are in good agreement with the crystal structure. The thermal gravity (TG) data indicate that there are four decomposition steps with three endothermic peaks. The final product of the thermal decomposition may be Fe(C2H8N2)SO4.
