摘要:

桥硫酚基团之间的顺磁性Ni(II)离子的磁交换相互作用的能力进行了检查。为此,双核和三核镍(II)配合物的制备和充分的IR和紫外-可见光谱,X-射线晶体学,静态磁化测量和高场电子自旋共振(HF-ESR)的特点。我们比较了两种Ni(II)配合物的结构和磁性,并讨论了磁性相互作用和化学键之间的关系。

英文摘要:

The ability of bridging thiophenolate groups to transmit magnetic exchange interactions between paramagnetic Ni(II) ions has been examined. For this purpose, dinuclear and trinuclear Ni(II)-complexes were prepared and fully characterized by IR- and UV-vis spectroscopy, X-ray crystallography, static magnetization measurements and high-field electron spin resonance (HF-ESR). We compare structural and magnetic properties of the two Ni(II)-complexes and discuss the relationships between magnetic interactions and chemical bonding.
