摘要：
Theoretical methods based on density functional theory have been employed to analyze the exchange interactions in a Fe9W12 Polyoxometalate complex. The calculated values of the seven exchange coupling constants required by the molecular structure agree well with those reported previously for other Fe-III polynuclear complexes and give an S = 15/2 single determinant ground state, with a first excited state that has S = 5/2.
