 Title    Investigation of Structural Questions on Europium Compounds by Means o f 151 Eu Mössbauer Spectroscopy  
 Abstract    151 Eu Mössbauer spectroscopy permits the determination of the symmetry of the site in which Eu is accommodated. It has been shown that the 151Sm F3 source can be considered a monochromatic source. This source was used to measure the line width of Eu3+ in a site with cubic symmetry, i. e. in a Cs2NaEuCl6 crystal. The isomer shift of commercial compounds used as standards (anhydrous EuF3 and EuS) was also measured. In the case of Cs2N aE u(N 02)6 hexanitritoelpasolite the trivalent europium ion is accommodated in a site with perfect cubic symmetry. In E u(P 03)3 crystalline metaphosphate, the rare earth is located in a site which appears to be distorted with respect to cubic symmetry; this site has no threefold or fourfold symmetry axis.

 Title    Halogen-Elpasolithe, VI [1] Erste Iod-Elpasolithe, Cs^M™^ (B 1 = Li, Na) Halo-Elpasolites, VI [1] The First Iodo-Elpasolites, Cs2B I M III I6 (Bi=Li, Na)  
 Abstract    Some iodo elpasolites Cs2LiM m I6 (M 111 = Sc, Lu, Tm, Ho) and Cs2NaM I i I I6 (M»i = Sc, Lu, Tm, Er) have been prepared for the first time. According to Guinier-Simon X-ray powder photographs they belong to the elpasolite type structure (cubic K2NaAlF6-type and its tetra-gonal distorted variety: Cs2NaMIe) or to the Cs2LiGaF6-type structure (trigonal: Cs2LiMIe). The compounds Cs2LiTmX6 (X = CI, Br, I) are further characterized by Raman spectra and magnetic susceptibilities.
