 Title    Two Examples of Partial and Total Defects in the B a«Ln2Mo4O i6-Type: BaCu0 41 ■o,59Pr2Mo4 0 16 and BaBYb2Mo4Ojg  
 Abstract    Single crystals of (I) BaCu0.4iPr2M o4O 16 and (II) BaYb2M o40 16 have been prepared by flux technique. Both compounds crystallize with m onoclinic symmetry, space group C2h-C 2 /c with (I): a = 5.352(11), b = 12.888(2), c = 19.399(4) A; ß = 90.89(3)°; (II): a = 5.181(7), b = 12.467(3), c -19.350(3) Ä , ß -91.93(2)°, Z = 4. The crystal structure is characterized by i [ B a M 0 12]-chains along [010]. In the first case the M positions are occupied by copper by about 41%, in the second case these positions remain com pletely unoccupied. With respect to the crystal chemistry of the reference compound Ba(Cu0.22Mg() 78)Nd2Mo4O 16 all substan­ ces of the composition BaLn2M o40 16 should be written as Ba»Ln2Mo40 16 indicating the holes in th e^ B a M O i^ -c h a in s by ■.

 Title    Uber ein Barium-Lanthanoid-Oxozinkat-Platinat(IV): Ba17Ybi6Zn8Pt40 57 On a Barium Rare Earth Oxozincate-Platinate(IV): B a j 7 Yb 16Z n8Pt40 57  
 Abstract    Reactions of B a C 0 3, ZnO and Yb20 3 mixtures at temperatures up to 1300 °C using plati­ num crucibles led to yellow needles of B a17Y b 16Zn8Pt40 57. The compound crystallizes with a hitherto unknown tetragonal crystal structure, space group C-4h-I4/m, a = 22.731(1), c = 5.682(1) A , Z = 2. The crystal structure is characterized by P t 0 6 octahedra and tetragonal Z n 0 5 pyramids. Yb3+ shows a mono-capped trigonal prismatic coordination and Ba2+ several different coordination environments (C .N = 9 to 10, by O2"). The relationship to the Ba5Ln8M40 2i type is discussed.

 Title    Zur Kenntnis eines Barium-Lanthanoid-Aluminat-Zinkats: BaLuAlZn30 7 mit einem Anhang zu Ba2Er2Zn80 13  
 Abstract    Reactions of B aC 03, ZnO, Lu20 3 and A120 3 mixtures at temperatures up to 1500 °C led to small and colourless rods of BaLuAlZn30 7. The new compound crystallizes with hexagonal symmetry, space group CöV -P63mc, a = 6.273, c =10.161 A, Z = 2. In spite of small differences in the oxygen content BaLuAlZn30 7 is isotypic to Ba2Ln2Zn80 13. The crystal structure shows Zn2+ with tetrahedral, Lu '+ with octahedral and Ba:+ with anticuboctahedral coordination by 0 2~. It has been shown that parts of the [Zn3A107]5_ network are fragments of the ZnO structure. In consequence one oxygen atom is fourfold coordinated by zinc/aluminium. The space group of Ba2Ln2ZnxO i3 must be corrected to C6V -P63mc.

 Title    Synthese und Kristallstruktur von Lanthanoidzinkboraten L n Z n ^ O jo) mit Ln = Ce, Nd, Tb Synthesis and Crystal Structure o f Rare Earth Zinc Borates LnZn(B5O ]0) with Ln = Ce, Nd, Tb  
 Abstract    Single crystals o f the new compounds LnZn(B5O |0) (Ln = (A) C e3+, (B) N d3+, (C) T b '+) were obtained by using a B 20 3 flux technique. X-ray investigations led to space group C2h-P 2,/n (Nr. 14) with lattice parameters: (A) a = 874.5(1), b = 761.4(1), c = 950.0(1), ß = 92.80(1)°, (B) a = 868.6(2), b = 760.9(2), c = 946.0(2), 0 = 92.9 9 (2)°, (C) a = 858.2(2), b = 760.5(2), c = 939.3(2), ß = 93.56(2)°, Z = 4. The structure is isotypic with C oSm (B 5 O |0) and is characte­ rized by two-dimensional infinite 2 (B 5 O 10)5_ ions. Ln is tenfold coordinated by oxygen, and Zn2+ occupies distorted Z n 0 6 polyfiedra.
