 Title    Zur Synthese und Kristallstruktur von manganhaltigen Boratoxiden  
 Abstract    M nF e(B 03) 0 und MnAl0,5Yo,5(B03) 0 Synthesis and Crystal Structure of Manganese Borate Oxides: M nFe(B03) 0 and MnAlo.5Yo.5(B 0 3) 0 Single crystals of the compounds M n F e(B 0 3) 0 (I) and MnAlo.5Y o.5(B 03) 0 (II), were obtained by a B20 3 flux technique. I crystallizes with orthorhombic symmetry, space group D ^ -P n m a (Nr.62), a -939.92; b = 319.41; c = 939.11 pm; Z = 4 and II with monoclinic symmetry, space group C2h-P 2 i/n (Nr. 14). a = 325.6; b = 955.1; c = 929.2 pm; ß = 90.70° ; Z = 4. I is isotypic to the mineral Warwickite, while II is a distorded variant of this structure. All metal ions are octahedrally coordinated. Both structures contain isolated, trigonal planar B 0 3 units and oxygen atoms that are not coordinated to boron.

 Title    Synthese und röntgenographische Charakterisierung von zwei neuen Verbindungen des Ludwigit-Strukturtyps: Co5Sn(B0 3)2 0 4 und Co5Mn(B0 3 )20 4  
 Abstract    Synthesis and X -R ay C haracterization o f Two New Com pounds with Ludw igite-Structure: C o5S n (B 0 3)20 4 and C o5M n (B 0 3)20 4 The compounds Co5Sn(B 03)20 4 (I) and Co5M n(B03)20 4 (II) were prepared by using a B20 3 flux technique. Single crystals were investigated by X-ray diffraction and showed orthorhombic symmetry, space group D2h-Pbam (No. 55), I a = 944.4; b = 1233.8; c = 310.5 pm; Z = 2 and II a = 925.07; b = 1241.67; c = 305.24 pm; Z = 2. Both compounds are isotypic to the mineral Ludwigite. All metal point positions show an octahedral oxygen coordination. Co2+ and M4+ (M = Sn or Mn) occupy one point position statistically. Both structures contain isolated, trigonal planar B 0 3 units and oxygen atoms that are not coordinated to boron.

 Title    Cox 5Ti0 5(B 0 3) 0 and Co! 5Zro.5(B 0 3) 0  
 Abstract    Single crystals of Co15Tio.5(B 0 3)0 (I) and Coj 5Zr0 5(BO3)O (I I) were obtained by a B20 3 flux technique. Both compounds crystallize with orthorhombic symmetry, space group D -Pnma (Nr. 62), I a = 928.1; b = 311.1; c = 940.1 pm; Z = 4 and I I a = 949.5; b = 323.42; c = 934.7 pm; Z = 4. The compounds are isotypic to the mineral warwickite. All metal ions are octahedrally coordinated by oxygen ions. The structure contains isolated, trigonal planar B 0 3 units and oxygen that is not coordinated to boron.
