对自旋交叉化合物Fe(dpq)(py)2(NCS)2·H2O·py 和Fe(dpq)(py)2(NCSe)2·1.5H2O的研究

摘要

为了研究配体修饰对自旋交叉现象的影响,我们合成了两个Fe(Ⅱ)自旋交叉的配合物[Fe(dpq)(py)2(NCS)2]·H20·py和[Fe(dpq)(py)2(NCSe)2]·1.5H2O,(dpq=二吡嗪[2,3-f:2＇3＇-h]喹喔啉,py=吡啶).通过对这两个配合物磁性质和穆斯堡尔谱的研究,发现和用邻啡咯啉配体合成的配合物比较,配体的修饰对自旋交叉性质以及其临界温度都有着显著影响.%In order to study the influence of modification from ligand on spin crossover behavior, two Fe (Ⅱ) complexes(py)2 (NCSe) 2 ] · 1.5H2O have been synthesized. The magnetic measurements and Mossbauer spectroscopy for thesecomplexes reveal significant effects on the type and critical temperature of spin conversion as a result of ligandreplacement of phen (phen = 1, 10-phenanthroline) by dpq.``
