	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.
