)是MCE的理想自旋中心,因为它具有很高的各向同性自旋,然而,4f电子的内部性质阻碍了它们之间的磁通信。混合金属3d-4f方法应该具有更好的磁相互作用的优点,因此,在优选的铁磁情况下具有更大的地自旋。我们已经用这种方法制备了具有大MCE的钴(II)(s=3/2)和镍(II)(s=1)钆膦酸盐配合物。
) is the ideal spin center for MCEas it has a high isotropic spin; however, the internal natureof the 4f electrons hampers the magnetic communicationbetween them. A mixed-metal 3d–4f approach should havethe advantage of a better magnetic interaction and thus,a larger ground spin in the preferred ferromagnetic case. Wehave used this approach to make cobalt(II) (s=3/2) andnickel(II) (s=1) gadolinium phosphonate complexes withlarge MCEs.
