Abstract
Single crystals of NH4LiGeF6 (I) and (NH4)(4)Li-2(GeF6)(3) (II) are studied by X-ray diffraction analysis [automated diffractometer, MoKalpha radiatio n, graphite monochromator, anisotropic least squares refinement to R = 0.05 4, R-w = 0.052 (I) and R = 0.038, R-w = 0.035 (II)]. Packing modes are cons idered for the structural units in crystals, The types of internal motions of ionic complexes in I are determined in the temperature range 170-400 K, and the corresponding activation energies are estimated.
