 Title    Synthese und Kristallstruktur von Dibariumzink-bis(cyclotriborat) Ba2Zn(B30 6)2  
 Abstract    Single crystals of the new compound Ba2Zn(B30 6)2 were obtained by using a B20 3 flux technique. They crystallize in an as yet unknown structure type. X-ray investigations led to space group Cj'-Pl (Nr.2) with lattice parameters a = 715.5(2), b = 720.5(2), c = 1178.9(4), a = 78.96(2)°, /3 = 85.45(2)°, j = 60.12(1)°, Z = 2. The structure is characterized by iso­ lated (B30 6)3_-rings and contains two ninefold coordinated Ba-sites. Zn2+ is tetrahedrally coordinated by oxygen. The relation to the crystal structures of high-temperature BaB20 4 and Ba2Ca(B30 6)2 is discussed.

 Title    Kristallstrukturuntersuchung am Barium-Yanadyl-Vanadat: Ba2(V 0)V 20 8 Crystal Structure Investigation of the Barium Vanadyl-Vanadate: Ba2(V 0 )V 20 8  
 Abstract    Single crystals of Ba2(V 0)V 20 8 have been prepared by solid state reactions of Ba2V 20 7, V 9O 1 and V ^ 05 in sealed silica tubes. This compound crystallizes with monoclinic symmetry, space group C 1 -P 2 ,, a = 8.1174(9), b = 5.9699(9), c = 9.2903(9) A , ß = 113.94(1)°, Z = 2. V 5+ shows tetrahedral coordination. V 4+ inside ^ [V (3)0 4] chains is characterized by a square pyramidal coordination with a short apical V-O distance of 1.6 A typically for vanadyl groups. Ba2(V 0)V 20 8 represents a new structure type and is not isotypic to Sr2(V 0)V 20 8.

 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    Ba2KZn3(B306)(B60 13)  
 Abstract    Single crystals of the new compound Ba2KZn3(B30 6)(B60 | 3) were obtained by using a B20 3 flux technique; they crystallize in an as yet unknown structure type. X-ray investigations led to the space group C '-P l (Nr.2) with lattice parameters a = 705.2(2), b = 712.5(2), c = 1880.3(6), a = 93.43(3)°, ß = 90.72(2)°, 7 = 119.57(2)°, Z = 2. The structure contains (B30 6)3~-rings and a new discrete (B60 13)8~ anion, which is composed of two B 0 4 and two B20 5 units. Zn-+ is tetrahedrally coordinated by oxygen and two out of three tenfold coordinated Ba-sites are statistically occupied by Ba2+ and K+.

 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.

 Abstract    Ba6Pr2Co40 15 (I) and Ba5SrPr2Co40 15 (I I) have been prepared by high temperature C 0 2-L A S E R techniques. Both compounds crystallize with hexagonal symmetry, space group C£v-P63mc, (I): a = 11.814(1), c = 7.100(2) A ; (II): a = 11.646(1), c = 6.8602 A , Z = 2. It is remarkable that the strongly reducing Pr3+ can coexist with the more oxidizing Co3+.

 Title     
 Abstract    Single crystals of BaCuTe03T e 0 4 have been prepared by crystallisation from melts. X-ray investigations lead to orthorhombic symmetry, space group C2v-Ama2, a = 5.4869(8), b = 15.412(1), c = 7.2066(4) A , Z = 4. This compound represents a new structure type, containing B aO 10, C u 0 5, T e 0 6 and T e 0 4 polyhedra. The lone pair (E) of TeIV completes the TeIV0 4 polyhedron to a trigonal T e 0 4E bipyramid. The Te to E distance is estimated by calculations o f the Coulomb terms of lattice energy to 1.43 A .

 Abstract    Two new alkaline earth vanadyl compounds, Sr2(V 0)(A s 0 4)2 (I) and Ba2(V 0)(P 0 4)2 (II), have been prepared by solid state reactions in closed quartz tubes and characterized by sin­ gle crystal X-ray diffraction methods. Crystal data: (I): monoclinic, C ,h -12/a, a = 6.873(2), b = 16.307(4), c = 7.196(2) A, ß = 115.67(2), Z = 4; (II): monoclinic, C^-I2, a = 9.471(2), b = 5.443(1), c = 16.972(4) Ä, ß = 101.65(2), Z = 4. (I) is isotypic to Sr2(V 0)V 20 8 and Sr2(V 0)(P 0 4)2. (II) shows significant differences to the strontium compounds as well as to Ba2(V 0)(V 0 4)2. The differences of the crystal chemistry and the similarity of (II) to Ba2(V 0)(P 0 4)2 H20 are discussed.

 Title    Zur Kenntnis eines Barium-Oxoniobat-Tellurats: Ba2 Nb2TeOi<) On a Barium-Oxoniobate-Tellurate: Ba2Nb2TeO,0 B  
 Abstract    Single crystals of Ba^NbiTeO,,) have been prepared by solid state reactions in air. X-ray investigations led to orthorhom bic symmetry, space group D ^-Pbca, a = 7.242(4), b = 12.433(3), c = 9.932(3) Ä. Z = 4. Nb""'* and Te6+ show octahedral coordination by O '-. The crystal structure is characterized by planes of edge-and corner-sharing NbOh-and TeOfloctahedra. It is shown that in spite of nearly identical lattice constants of Ba2Nb2TeO |0 with compounds of the composition M() 5BaNbTe20 9 the so far unknown crystals of these substances may not be derived from the Ba^Nb^TeOio type.

 Title    Zur Kristallchemie der Barium-Oxometallat-Tellurite: Ba2M6Te202i (M = Niob und Tantal) On the Crystal Chemistry of the Barium Oxometallate-Tellurites Ba-,M6Te  
 Abstract    Single crystals of Ba2Nb6Te20 2| (I) and Ba2Ta6Te20 2| (II) have been prepared by solid state reactions in air. X-ray investigations led to monoclinic symmetry, space group C 3h -C2/m, (I): a = 16.699(3), b = 5.671(2), c = 9.611(2) A, ß = 96.92(2), (II): a = 16.655(8), b = 5.667(2), c = 9.576(4) Ä, ß = 96.64(7), Z = 2. N b5+ or Tas+ show octahedral and Te4+ a one sided triangular coordination by O 2 -. The position and distance of the lone pair on Te4+ have been estimated by calculations of the Coulomb terms of the lattice energy. The polyhedron around Ba2+ may be described by a triply capped BaO^cube. The crystal structures are dominated by a ^ [Nb60 2l] l2~ network with incorporated Ba~+ and Te4+ ions.
