A new μ 3 ‐O triiron(III) complex [Fe 3 O(OBz) 6 (CH 3 OH) 3 ](NO 3 )(CH 3 OH) 2 (HOBZ = benzoic acid) has been synthesized, its structure has been determined and variable temperature magnetic susceptility has also been measured. In the molecule, three iron atoms formed an equilateral triangle with μ 3 ‐O in center. The fitting to the magnetic susceptibility showed that an intramolecular antiferromagnetic exchange interaction occurred between iron atoms with J=‐ 25.51 cm −1 , and a weaker intermolecular autiferromagnetic exchange interaction occurred with zJ' = −2.30 cm −1 .
