摘要：

The structure of lead(II) tetrafluorostannate(II) (PbSnF4) prepared by hydrothermal was determined. The parameters of the orthorhombic unit cell are a = 22.845 (2) angstrom, b = 5.850 (2) angstrom, c = 6.021 (2) angstrom, V = 804.6 (6) angstrom 3, rho-calc = 6.63 g/cm3, z = 8, space group Aba2. The high F- mobility in this compound was found to be correlated to the possibility for tin atoms to have two alternative fluoride ions coordinations, and/or to the great number of partially occupied F sites.
