Theoretical Research on Optical, Thermal and Magnetic Properties of Ni(pz)_4Cl_2 Complex

利用d8（D4h*）全组态混合统一晶场理论计算了Ni（pz）4Cl2型络合物中Ni2+离子的吸收光谱、顺磁磁化率及Schottky热容．理论结果与实验一致．

In this paper, we have calculated analyzed theoretically the absorption spectra, the low-temperature Schottky heat capacity and the paramagnetic sllsceptibility of Ni2+ ions in Ni(pz)4Cl2 (pz=Pyrazole) complex, by using the complete configuration mixing unified crystal field theory for d8(D4h*), and the theoretical results agree with the experimental data very well. Thus we can give a complete and reasonable theortical interpretation of the optical, thermal and magnetic properties of the Ni2+ ions in Ni(pz)4Cl2 complex.
