摘要：
The local structure of the rhombic Cu2+ center in Cu0.5Zr2(PO4)(3) phosphate is investigated by using the high-order perturbation formulas of electron paramagnetic resonance (EPR) parameters, g-factors g(i) (i = x, y, z), and hyperfine structure constants A(i) for 3d(9) ions in rhombically elongated octahedral symmetry. According to the studies, the local axial distortion angle Delta alpha (approximate to 5.1 degrees) and the planar bond angle theta (approximate to 83.8 degrees) in [CuO6](10-) cluster was obtained. The theoretical EPR parameters based on the aforementioned local structure parameters show good agreement with the observed values, and some improvement have been made as compared with the previous studies.
