 Title    Eine neue Verbindung im System Ba/Ln/Zn/Pt/O: Bs^Sn^Zi^PtOis On a New Com pound in the System B a/Ln/Zn/Pt/O : Ba4Sm 4Z n3P tO |5  
 Abstract    Reactions of mixtures of B aC 03, ZnO, Sm20 3 (3:5: 1) heated in platinum crucibles up to 1250 °C led to big black single crystals of Ba4Sm4Zn3P t0 15. The new compound crystallizes with hexagonal symmetry, space group C^-Pö^mc, a = 1 L657, c = 6,789 A , Z = 2. It is isotypic with Ba6Nd2Al4O l5 but shows an ordered Pt4+ and Zn2+ distribution over the aluminium positions. The octahedrally coordinated barium sites of the Ba6Nd2Al40 15 type are occupied by Sm3+. In comparison to compounds of the composition Ba6Ln2M40 15 (M = Al, Fe, Co), Ba4Sm4Zn3PtOi5 is the first example containing different oxidation states at the M '+ positions.
