 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    On the Crystal Structure o f (C u ,M n )3 66M o30 12  
 Abstract    Single crystals o f (Cu,M n)3 66M o 30 12 have been prepared in sealed copper tubes. X-ray investiga­ tions lead to orthorhombic symmetry, space group Dih-Pnm a, a = 5.1541(9), b = 10.788(2), c = 18.114(3)) Ä , Z = 4. (Cu,M n)366M o 30 12 is iso­ typic to NaCo2 31M o 30 12 and (C u,C o)3 75M o 30 12 with split positions for two o f the metals.

 Title    On the Crystal Structure of (Cu, M n )U M o 30 12  
 Abstract    Single crystals of (C u,M n)U M o30 12 have been prepared in sealed copper tubes. X-ray investiga­ tions lead to hexagonal symmetry, space group C|h-P63/m, a = 9.7895 (13), c = 6.202(1) A , z = 2. (C u ,M n)U M o30 12 is isotypic to CdThM o30 12. Calculations of the Coulomb terms o f lattice energy with respect to different oxidation states o f copper, molybdenum and uranium and the pre­ viously described pair of isotypic compounds of CdThM o30 12 to Na2ThRe60 24 are discussed.

 Title    A nne  
 Abstract    The compounds M nCo(B20 ?) (I) and M nM g(B20 5) (II) were prepared by using B20 3 flux techniques in an argon atmosphere. X-ray investigations on single crystals showed triclinic symmetry, space group C' -P i, I: a = 320.94(10), b = 619.20(11), c = 939.0(2) pm, a = 104.38(2)°, ß = 90.76(2)°, 7 = 92.046(14)° and II: a = 318.97(7), b = 619.8(2), c = 936.7(2) pm, q = 104.47(2)°, ß = 90.60(2)°, 7 = 91.98(2)° Z = 2. Their structures are isotypic with C o2(B20 5). All metal ions are octahedrally coordinated by six oxygen atoms. The structures contain diborate anions B ^ 4 -. Each boron atom is threefold coordinated by oxygen. Synthese und Kristallstruktur von manganhaltigen Pyroboraten: MnCo(B20 5) und MnMg(B20 5)

 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.
