 Title    Neue Einsichten zur Stabilisierung des Hulsit-Strukturtyps am Beispiel von Mnl,2MnIII( B 0 ,) 0 2 und Mn,lSrMnlll( B 0 ,) 0 , New Insights into the Stabilization of the Hulsite Structure During Crystal Structure Determination of M nII2M nIII(B 0 3)0-) and MnllSrM nIII(B 0 3) 0 2  
 Abstract    The compounds MnII2M nIII(B 0 3)02 (I) and MnnSrM nm(B0 3)0 2 (II) were prepared by using a B20 3 flux technique. Single crystals were investigated by X-ray diffraction. I showed ortho-rhombic symmetry, space group D2h -Pbam (No. 55), a = 926.0; b = 1241.5; c = 304.96pm ; Z = 4 and II monoclinic symmetry, space group C2h -P2/m (No. 10), a = 1107.5; b = 311.04; c = 542.93 pm, ß = 95,10(2)°; Z = 2. M n '^ M n '^ B O d O i is isotypic with the mineral Lud­ wigite while MnnSrM nm(B0 3)0 2 is isostructural with the mineral Hulsite. In the structure of M niI2M nlll(B 0 :,) 0 2 (I) all metal point positions showed octahedral oxygen coordination, one point position is occupied by M nu . The structure of M nll2Sr2M nlll2(B O 02O 4 (II) contains five octahedrally coordinated metal sites, three of them statistically occupied by Mn:+ or Mn '+ and Sr2+. The incorperation of S r + seems to be responsible for the Hulsite structure. Both structures contain isolated, trigonal planar B 0 3 units and oxygen atoms that are not coordinated to boron.

 Title    Isolierte MnCl6-Oktaeder im Oxohalogeno-Vanadat Ba5(Mg0,4Mn0,6)(V2O7)2MnCl6 Isolated MnCl6 Octahedra in the Oxohalogeno Vanadate Ba5(M g0 4Mn0 6)(V20 7)2MnCl6  
 Abstract    Single crystals o f Ba5(M g0 4Mn0 6)(V20 7)2MnCl6 have been prepared by solid state reactions of M g C 0 3, Mn20 3, V20<i and BaCl2 -2H20 below the melting point of BaCl2. The new vanadium oxide chloride crystallizesowith monoclinic symmetry, space group C2h-P2/c, a = 13.345(4), b = 5.711(2), c = 15.859(4) Ä, ß = 113.69(2)°, Z = 2. Special features of the crystal structure are isolated MnCl6 octahedra and layers created by divanadat groups and (M g,M n)06 octahedra. The ^ [(Mg,Mn)V20 7] nets of Ba5(Mg0 4Mn0 6)(V20 7)2MnCl6 are discussed with respect to other oxohalogeno vanadates containing divanadate groups.

 Title    Ein [Ba(Ca,Mn)06]-Gerüst mit eingelagerten V-O-V-Gruppen in der Kristallstruktur von Ba(Ca0,6Mn0,4)V20 7 A [Ba(Ca,Mn)06] Framework with Incorporated V-O-V Groups in the Crystal Structure of Ba(CaQ 6Mn0 4)V20  
 Abstract    Single crystals of Ba(Ca<).6Mn0 4)V20 7 have been prepared by crystallization from melts. X-ray investigations revealed a new quaternary vanadium oxide of the type BaMV20 7. The M positions are occupied statistically by Ca2+ and Mn2+. The compound crystallizes wi|h orthorhombic symmetry, space group D^-Pnma, a = 15.429(2), b -5.7005(12), c = 7.364(2) A, Z = 4. The crystal structure can be interpreted as a [Ba(Ca,Mn)06] network with incorporated V-O-V groups. Considering the nearest O2-neighbours of the incorporated vanadium, the V-O-V groups are complemented to give V20 7 divanadate units. Ba(Ca« 6Mn0 4)V20 7 is isotypic to BaMV20 7 (M=Ca,Cd) but not to BaMnV20 7.

 Title    Catalytic Oxidation of a Trialkyl-Substituted Phenol and Aniline with Biomimetic Schiff Base Complexes  
 Abstract    The catalytic oxidation of 2,4.6-tri-f6rr-butylphenol and 2,4,6-tri-te/-r-butylaniline with mo­ lecular oxygen and rerf-butylhydroperoxide was investigated using biomimetic Mn-, Fe-and Co-complexes as catalysts. The catalytic activity and product distribution were determined and compared with those observed in the reactions of the well-known Co(salen) complex.

 Title    Quaternary Selenidogermanates(IV) A3[AgGe4Se10]*2H2O and A2[MnGe4Se10]*3H2O (A = Rb, Cs) with Open Framework Structures  
 Abstract    Hydrothermal reaction of Ge and Se with Ag(CH3COO) in the presence of alkali metal carbonates affords the open framework selenidogermanates(IV) A^fAgGejSeiol ^H^O (A = Rb, Cs), 1 and 2, which contain corner linked adamantane-like Ge4Seio cages and AgSe4 tetrahedra. The analogous reaction with Mn(CHiCOO)2 yields the isostructural tetragonal compounds A2[MnGe4Seio]-3 H2 0 (A = Rb, Cs), 3 and 4. The cations are sited at a general position in the channels of the silver bridged anionic framework of 1 and 2 and exhibit a disordered pattern of occupation (s.o.f. = 0.75) with one of the two crystallographically independent water oxygen atoms 0 (2) (s.o.f. = 0.25). In contrast, the Rb+ cations in 3 are disordered over all three cation/oxygen sites, and the cation/water occupation pattern is fully reversed for the larger Cs+ cations in 4 in comparison to 1 and 2.
