Abstract:

In this paper, we have calculated analyzed theoretically the absorption spectra, the low-temperature Schottky heat capacity and the paramagnetic susceptibility 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.

Key words: Ni(pz)4Cl2, Absorption spectra, Susceptibility, Schottky heat eapacity
