摘    要:在合成Rn[Ni(bbdt)2]系列配合物的基础上,通过EPR谱、XPS谱、变温磁化率和室温电导率的测定。研究了配合物的电磁学性能.结果表明,在Rn[Ni(bbdt)2](n=0,0.5,1,2)系列配合物中,n=0,0.5,1对应的配合物室温EPR谱中有特征的单电子信号;XPS测定的结合能数据说明,中心Ni离子对阴离子部分的荷电量不敏感。而配体S原子的结合能随荷电量有较大变化;n=0,0.5对应的配合物表现出较好的电磁学性能。

关 键 词:镍配合物 Rn[Ni(bbdt)2] 电磁学性能 1  2-二硫代乙烯 变温磁化率 室温电导率 结合能

Abstract:The electrical and magnetic properties of coordination compounds R n [Ni(bbdt) 2] have been studied based on EPR spectra, XPS spectra, magnetic susceptibility at different temperature and conductivities at room temperature. It shows that there are characteristic single electron signals in ESR spectra for the compounds R n [Ni(bbdt) 2] ( n =0,0.5,1). The binding energy obtained from XPS shows that the central Nickel ion is not sensitive to the charge number of anion, while the binding energy of sulfur changes with the charge number of anion. It can be concluded that the compounds R n [Ni(bbdt) 2] ( n =0,0.5) exhibit better electrical and magnetic properties.
Keywords:1  2-ethylenedithiolato  coordination compound  electrical and magnetic properties
