摘要	The electron paramagnetic resonance (EPR) parameters (zero-field splitting D, and g-factors g(parallel to), g(perpendicular to) ?) for d(8) Ni2+ ions in tetragonal ligand fields KZnF3: Ni2+ or in trigonal ligand fields CdCl2(CdBr2 and CsMgI3) : Ni2+ complexes have been systematically studied on the basis of the 45 x 45 complete energy matrices. The local structural distortion parameters of the crystals obtained are Delta R-1 = 0.0355 angstrom, Delta R-2 = 0.0296 angstrom for KZnF3 : Ni2+, Delta R = 0.1730 angstrom, Delta theta = -1.5695 degrees for CdCl2: Ni2+, Delta R = -0.0381 angstrom, Delta theta = -2.6236 degrees for CdBr2 : Ni2+ and Delta R = -0.0267 angstrom, Delta theta = -1.8967 degrees for CsMgI3: Ni2+. The calculated results show that the local structures exhibit elongation distortion for KZnF3 : Ni2+ and compression distortions for Ni2+ : CdCl2 (CdBr2 and CsMgI3) systems. Further, the relationships between ZFS parameter D and structural parameters (theta, R) are studied and the influence of the orbit reduction factor k on g-factors (Delta g,g) are discussed.
