摘要	The relationship between the impurity structures and the electron paramagnetic resonance (EPR) parameters D, (a-F) have been studied by diagonalizing the complete energy matrices for Mn2+ ion in [Mg(H2O)(6)]SnCl6 single crystal in a trigonal ligand field within a weak-field-representation. It is shown that the local lattice structure around Mn2+ ion in [Mg(H2O)(6)]SnCl6 exhibits an elongation distortion which is different at 290 K and 77 K. The local structure parameters R = 2.223 +/- 0.027 angstrom, theta = 52.966 +/- 0.004 degrees and R = 2.205 +/- 0.030 angstrom, theta = 53.155 +/- 0.047 degrees for Mn2+ ion in [Mg(H2O)(6)]SnCl6 are determined at different temperatures 290 K and 77 K, respectively, and EPR parameters D and (a-F) can also get a satisfactory explanation simultaneously.
