Abstract

Complex formation of 5--butyl-1,3-phenylene bis(-butyl nitroxide) and rare-earth (RE) metal ions gave a linear chain where each nitroxide O atom is directly bonded to the RE ion. The bridge was proven to be a ground triplet molecule in the complexes. A hysteresis loop was recorded below 2.8 K as a single-chain magnet for the RE = Tb derivative.

摘要

5-丁基-1,3-亚苯基双（丁基氮氧化物）与稀土（RE）金属离子形成的配合物产生了一条线性链，其中每个氮氧化物的O原子直接与RE离子键合。已证明该桥在配合物中是基态三重态分子。对于RE = Tb衍生物，在2.8 K以下记录到了作为单链磁体的磁滞回线。
