Abstract

Synthesis and structure of dinuclear complexes [{Fe^III(L⁵)}b{Fe^III(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.
