英文摘要When Cu2+ ion occupies the trigonal Al3+ (II) site in guanidinium aluminium sulphate hexahydrate (GASH) (C(NH2)(3)Al(SO4)(2)center dot 6H(2)O) crystals, the trigonal Al(H2O)(6)(3+) octahedron in the host GASH crystal changes to the tetragonally-elongated Cu(H2O)(6)(2+) octahedron in the impurity center due to the Jahn-Teller effect. The tetragonal distortion (characterized by Delta R=R-parallel to-R-perpendicular to, where R-vertical bar and R-perpendicular to represent the metal-ligand distances parallel with and perpendicular to the C-4 axis) of this Cu(H2O)(6)(2+) cluster is studied by calculating its spin-Hamiltonian parameters (g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to) and A(perpendicular to)) from two theoretical methods, the complete diagonalization (of energy matrix) method (CDM) and the perturbation theory method (PTM). Both methods are based on the cluster approach in which the admixture between the d orbitals of 3d(n) ion and the p orbitals of ligand ion is considered. The calculated results show that both methods can be used to calculate the spin-Hamiltonian parameters and to determine the structure of 3d(9) clusters in crystals. These results are discussed.
