摘要：

The trinuclear complex [ZnCl(mu-L)Dy(mu-L)ClZn]PF6 exhibits a single-molecule magnetic behaviour under zero field with a relatively large effective energy barrier of 186 cm(-1). Ab initio calculations reveal that the relaxation of the magnetization is symmetry-driven (the Dy-III ion possesses a C-2 symmetry) and occurs via the second excited state.
