Sulfato and carbonato bridged dinuclear iron(Ⅲ) complexes {2[(TPA)_2Fe_2O(SO_4)]·(ClO_4)_2·1.5H_2O (1), [(TPA)_2Fe_2O(CO_3)](ClO_4)_2·CH_3OH (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 P2_1/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 P2_1/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.
