Complexes that Feature Chelating Guanidine Ligands: Structural Characteristics and Molecular Magnetism
Several new mono- and dinuclearcomplexes of CoII and NiII with chelatingguanidineligands were synthesized. The molecular structures for most of the complexes in the crystalline state were derived from single-crystal X-ray diffraction, and some characteristicstructural details are discussed. The molecularmagnetism was further studied by superconducting quantum interference device (SQUID) measurements
合成了几种新的带有螯合胍配体的 Co II 和 Ni II 的单核和双核配合物。大多数处于结晶状态的配合物的分子结构来自单晶 X 射线衍射,并讨论了一些特征结构细节。通过超导量子干涉装置 (SQUID) 测量进一步研究了分子磁性。除了实验之外,还进行了量子化学计算。最后,讨论了其中一种配合物的顺磁 NMR 谱,这表明 1 JC,H 相关实验是可能的。
