Slow Magnetic Relaxation in Novel Dy4 and Dy8 Compounds

Pei‐Pei Yang, Xi-Feng Gao, Haibin Song, Sai Zhang, Xuelan Mei, Licun Li, Dai‐Zheng Liao

Abstract

Two novel dysprosium(III) clusters have been prepared and structurally characterized. One has a tetranuclear core with a rare zigzag arrangement, and the other is an unprecedented octanuclear cluster with six triangular Dy(3) units sharing vertices. Both dysprosium(III) clusters possess frequency-dependent on alternating-current magnetic susceptibilities, indicating possible single-molecule magnet behavior.
