| Abstract: | Synthesis and structure of dinuclear complexes [{FeIII(L5)}b{FeIII(L5)}](BPh4)2, where L5 is a pentadentate Schiff-base ligand, b is a bidentate N-oxide bridging ligand based on bipyridine, is reported. Magnetic behavior is investigated in terms of the magnetic susceptibility, magnetization, and Mössbauer spectroscopy revealing that the complexes are high-spin over the whole temperature region. |
