Abstract
Regions of homogeneity were determined for the systems LizYClHx, LizYCLCx and LizYCLOx. Cell parameters for the different samples are given and trends, especially for the length of the c axis, are discussed. Temperature dependent Guinier-Simon investigations on different LizYClHx compounds show a shortening of the c axis at 480°C, which must be interpreted as a deintercalation of lithium. Y2Cl3 forms upon decomposition of LizYClHx at 1100°C. Conductivity measurements on a pellet of 7Li0.15YClD0.65 give a specific resistance of 2.2 × 10-1 ω·cm at 298 K which hints at electronic conductivity. Cell parameters, atomic positional parameters and occupation factors gained from a neutron powder diffraction experiment on 7Li0.15YClD0.65 are reported. The line shape of 7Li-NMR powder spectra is consistent with lithium at a definite lattice site. For all samples motional narrowing starts below room temperature. In the system LizYClC0.5 pronounced diffusion induced peaks of the spin-lattice relaxation rate T-11(T) of 7Li are observed above room temperature which exhibit the temperature dependence typical of disordered systems. In Li0.15YClD0.65 the 7Li spin-lattice relaxation rate, at the applied field of 4.7 T, does not show a significant peak but a continuous increase with temperature in the range from 150 K to 800 K.
