摘要：

A Dy-2 single-molecule magnet was isolated using a mixed ligand strategy in which the Dy-III ions adopt distinct coordination environments. This leads to two unique relaxation modes due to a single-ion type relaxation mechanism. Energy barriers were obtained from individually fitting the overlapping peaks.
