摘要：

K(2)SnCl(6 )single crystals doped with Cu were grown by the evaporation of saturated solution. The electron magnetic resonance (EMR) of the Cu2+ ion in the crystal has been investigated by using an X-band spectrometer. The rotation pattern in the crystallographic plane together with spin Hamiltonian parameters of Cu2+ ion in K2SnCl6:Cu single crystal shows that the local site symmetry of the Cu2+ ion is cubic at room temperature. The calculated spectroscopic splitting factor g of Cu2+ impurity ion is 2.1908(+/- 0.0007). The hyperfine constants of Cu2+ impurity ion due to the Cu-63 and Cu-65 isotopes in K2SnCl6:Cu crystal are 0.83(+/- 0.01)x10(-4) cm(-1) and 0.89(+/- 0.01)x10(-4) cm(-1), respectively. It turns out that the Cu2+ ion substitutes for the K+ ion without any nearby charge compensation.
