Based on the the crystal structure parameters of the complex 1, the bond angles of Mn(1)-O(2)-Mn(2) and Mn(3)-O(4)-Mn(2) are close to the bond angle of Mn(4)-O(8)-Mn(2), there are quite modest differences between the magnetic coupling constants of Mn(1), Mn(3) and Mn(4) respectively with Mn(2), hence, we hypothesize one J1 value between them is reasonable.

According to the crystal parameters, the bond angles of Mn (1)-O (2)-Mn (2), Mn (3)-O (4)-Mn (2) and Mn (3)-O (4)-Mn (2) are close to each other, which indicates that the magnetic coupling constants between Mn (1), Mn (3), Mn (4) and Mn(2) are comparable. Hence, it¡¯s reasonable to suppose that they have equal J1 value.
