The magnetic property of μ 3 ‐oxotriiron(III) complex [Fe 3 O(OBz) 6 (CH 3 OH) 3 ](NP 3 )‐(CH 3 OH) 2 (HOBzbenzoic acid) has been studied. We use isosceles triangle model and molecular field correction to fit the experimental magnetic susceptibility data. It shows that an intramolecular antiferromagnetic exchange interaction occurs with J = ‐31.27 cm −1 , J '= ‐27.26 cm −1 , and a weaker intermolecular antiferromagnetic exchange interaction occurs with zJ' = ‐ 3.76 cm −1 . We give the d 5 ‐ d 5 ‐ d 5 energy level diagram of triiron(III) complex as a function of J'/J. From the diagram we can get the total spin S T of the complex as 1/2 in the ground state.
