Abstract

The trinuclear complex [ZnCl(μ-L)Dy(μ-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 DyIII ion possesses a C2 symmetry) and occurs via the second excited state.
