Magnetic Property of -Peroxo-bis[bis(diphenylglyoximato)iron()]

[摘要] It was observed that the magnetic moment for iron in [(DPGH)2FeO2Fe(DPGH)2], the oxygenation product of a octahedral iron(¥±) complex, [Fe(DPGH)2(NH3)2], decreases with decreasing temperature from ¥ì = 3.60 B.M (Bohr Magneton) per iron at 298¢ªK down to ¥ì = 1.65 B.M per iron at 4.2¢ªK. This observation may be explained by a weak antiferromagnetic coupling between two iron(¥²) atoms of intermediate spin state (S = 3/2) in the molecule with the coupling constant J = -l cm-1.
