 Title    Zur Kristallchemie von Telluraten mit Mn2+ im kationischen und anionischen Teil der Kristallstruktur: (Mn2?4Cuo,6)Te06, Ba2M nTe06 und Pb(Mn0,5 Te0,5 )O3 On the Crystal Chemistry of Tellurates Containing Mn2+ in the Cationic and Anionic Part of the Crystal Structure: (Mn2 4Cu0 6)Te06, Ba2MnTe06 and Pb(Mn0 5Te0 5) 0 3 L  
 Abstract    Single crystals of (Mn2.4Cu0 6)Te06 (I), Ba2MnTe06 (II) and Pb(Mn0 5Te0 5) 0 3 (III) have been prepared by crystallization from fluxes. X-ray investigations led to rhombohedric sym­ metry (I): R3, (II): R3m with the trigonal lattice constants (I): a = 8.826(1), c = 10.687(2) Ä, Z = 2. (II): a = 5.817(8), c = 14.244(3) A, Z = 3. Compound (III) crystallizes with cubic symmetry P43m, a = 4.045(3) A, Z = 1. (I) is the first example of a manganese(II) tellurate and belongs to the structure type of A3X 0 6 compounds like (Mn2In)Sb06, Mn3W 0 6 and Ca3U 0 6. (II) exemplifies an ordered and (III) a disordered variation of the perovskites.

 Title    Ag+ als Substituent eines Alkalimetalls in Ag2SrMnV20 8  
 Abstract    Single crystals of Ag2 SrM nV20 8 have been prepared by reactions of metallic silver and a mixture of S rC 0 3, M nC 03 HoO and V ?0 5. X-Ray investigations showed monoclinic symmetry, space group Cfh-C2/c, a = 9.7022(9), b = 5.5882(5), c = 13.894(1), ß = 90.41(1)°, Z = 4. The crystal structure is isotypic to N a2BaCuV20 8 and includes V 0 4 tetrahedra, M n 0 6 octahedra as well as irregular A g 0 8 and S rO !0 polyhedra. Ag2SrM nV20 8 is characterized by a [MnV20 8] network incorporating Ag+ and S r + or a [Ag2V 2Ö 8] frame incorporating Mn2+ and Sr2+ ions. Ag+ is able to replace an alkali ion in the cationic part of the crystal structure.

 Title    Isolierte trigonale S r 0 6-Prismen verknüpfen Kagome-Netze im Strontium-Manganat(I V)-Tellurat( VI): SrMnTe06 Kagome Layers Connected by Isolated Trigonal Sr06 Prisms in the Strontium Manganate(IV) Tellurate(VI): SrMnTe06 L  
 Abstract    Single crystals of the hitherto unknown compound SrM nT e06 have been prepared from Sr(0H)2-8H20 , M n C 0 3(aq) and T e 0 2 in air by crystallization below the melt range. X-ray in­ vestigations showed hexagonal symmetry, space group D3h-P62m, lattice constants a = 5.143(1), c = 5.384(2) A, Z = 1. SrM nTe06 is characterized by staggered [(Mn/Te)60 18] Kagome layers along [001]. These layers are connected by Sr2+ ions, resulting in S r0 6 prisms isolated from each other. The structure is discussed with respect to the connection of Kagome nets in the quaternary oxides of the Ba3Ln40 9 type.
