 Title    Zur Kristallchemie der Oxoplatinate. Eine neue Phase der Zusammensetzung Sr4_j.Naj.PtO6 (jt = 0,33)  
 Abstract    On the Crystal Chemistry of Oxoplatinates. A New Phase of the Composition Sr4 _xN avP t0 6 (x -0.33) G. Tams, Hk. Single crystals of Sr3 67Na() 33PtO fi were prepared by heating oxide mixtures in closed silver tubes and investigated by X-ray single crystal techniques. It crystallizes with trigonal symme­ try, space group Dfd-R 3 c (Nr. 167) with a = 9.6617, c = 11.6580 Ä, Z = 6. Sr367Na()33P t0 6 belongs to the Sr4P t0 6 type and is isotypic to K4CdCl6. One point position characterized by a trigonal prismatic O 2-coordination is occupied by N a+ and Sr2+ statistically. The crystal structure is discussed with respect to the related compounds Sr3C u P t0 6 and Ca3 5Cu() 5P t0 6.

 Title    A Contribution to the Crystal Chemistry of Alcaline Alealine Earth Precious Metal Perovskites. Synthesis and Crystal Structure of NaBa4Cuo,5Pti,50 8  
 Abstract    Single crystals of the phase NaBa4Cu0 5P t1 s0 8 were prepared in closed silver tubes. The black and moisture sensitive crystals were investigated by four-circle diffractometer X-ray tech­ niques. They show trigonal symmetry, space group D2-P321, a = 10.0644, c = 8.3811 A, Z = 3 and belong to the perovskites. The typical M20 9 double octahedra are occupied by Pt4+ and Cu2+ in a different manner. Na+ is partly in and out of the centres of trigonal prisms of oxygen. These features will be discussed with respect

 Title    NaK9Tl13: Eine neue Verbindung an der Zintl-Grenze mit isolierten, von Thallium besetzten Tl17-Ikosaedern  
 Abstract    NaK9T l13 (a = 1152.0(1) pm, Im 3, Z = 1, RI -0.029, wR2 = 0.0724) has been prepared from the elements and characterized by single crystal X-ray diffraction. The title compound contains isolated T l12 icosahedra, which are centered by T1 atoms. The icosahedra are in an a-W-type arrangement.
