Abstract: Sulfato and carbonato bridged dinuclear iron(Ⅲ) complexes {2[(TPA)2Fe2O(SO4)]·(ClO4)2·1.5H2O (1), [(TPA)2Fe2O(CO3)](ClO4)2·CH3OH (2)} were synthesized at room temperature. The crystal structures were characterized by X-ray diffraction structural analyses. Complex 1 crystallized in the monoclinic space group P21/c with a=1.150(2) nm, b=2.659(5) nm, c= 2.933(5) nm, and β=99.40(3)°. The structure was determined at 293 K from 15.503 out of a total of 36.459 reflections with R=0.056 4, wR=0.110 6. Complex 2 crystallized in the monoclinic space group P21/c with a=1.136 8(3) nm, b=1.828 0(5) nm, c=2.054 2(5) nm, and β=94.867(5)°. The structure was determined at 293 K from 7.420 out of a total of 17.309 reflections with R=0.056 7, wR=0.136 2. Complexes 1 and 2 were compared with some (μ-O) dinuclear iron complexes in crystal structures and the UV-Vis spectra were recorded at room temperature.

Key words: Crystal structure, Dinuclear iron, UV-Vis spectrum
