 Title    Transphosphorylative Spin-Labeling Utilizing Diimidazolides of Pentavalent Phosphorus  
 Abstract    G e o r g e S o s n o v s k y a n d M a r i a K o n i e c z n y The reaction of the spin-labeled diimidazolide 1 with hydroxy and amino compounds was studied. Diimidazolide 1 was superior to the dichloridate 6 for the preparation of spin-labeled phosphates 3 and phosphorodiamidates 2. The spin-labeled phosphate 15 was synthesized through hydrolysis of 6 . Spin-labeled cyclophosphoramidates (10-13), analogs of the cytotoxic Endoxan, were prepared by the reaction of 1 and 6 with the appropriate difunctional nucleophile. Inductive effects of substituents in the imidazolyl m oiety on the transphosphorylation reaction were also studied. 0 0 0 0 R0p { N ^ f) 2 R O P (N r'r2)2 R 0P(0R> 2 RO PCIj I 2 3 6 0 o 1 1 / N OP (CH2)n N H 10 (n • 2 ,3) H 0 • II ,0 ROP r i i CH, ROP, n ' x h , 13

 Title    Electrochemical Syntheses, XVII [1] Ozone Synthesis by Electrolysis of Water  
 Abstract    Dimensionally stable lead dioxide anodes on a titanium substrate [2, 3] were tested for application in ozone electrosynthesis in a variety of aqueous electrolytes. At room tem-perature an ozone concentration of up to 13% by weight in the anodic gas composed of O3 and O2 is attained by using an aqueous phosphate electrolyte.

 Title    Vier verschiedene Koordinationspolyeder um Cu2+ im Oxid-Arsenat-Phosphat Cu0  
 Abstract    (Cu,M g)3(As1_xPJt:0 4)2 (x = 0,3) Four Different Coordination Polyhedra Around Copper in the Oxide-Arsenate-Phosphate C u0(C u,M g)3(A s,_xP,.04)2 (x = 0.3) Single crystals of CuO(Cu,Mg)3[(As0.7P0.3)O4]2 have been prepared by crystallization from melts. The compound crystallizes with triclinic symmetry, space group C '-P l, a = 6.372(4), b = 7.643(7), c = 8.175(5) A, a = 98.59(6), ß = 112.26(3), 7 = 99.03(3)°, Z = 2. CuO(Cu,Mg)3[(Aso)7Po 3)0 4]2 is isotypic to Cu4(P 0 4)20 . X-ray investigations show square planar C u 04 polygons, twisted tetragonal C u 0 5 pyramids, C u 05 bipyramids and elongated (Cu,M g)06 octahedra.

 Title    Die Synthese und Kristallstruktur des Borat-Phosphats: a -Zn3(B0 3)(P04) Synthesis and Crystal Structure of the Borate-Phosphate: Q-Zn3(B 0 3)( P 0 4)  
 Abstract    Single crystals of the compound a -Z n 3(B 0 3)(P 0 4) were obtained at 1050 °C by using B20 3, P20 5 and Z n C 0 3 as starting materials and subsequent cooling to 600°C with 20°C/h. X-ray investigations on single crystals yield a new crystal structure in the monoclinic space group Cm -(Nr. 8) with a = 972.5(2); b = 1272.0(3); c = 487.4(3) pm; 0 = 1 1 9 .8 0 (4)°; Z = 4. The structure contains isolated trigonally planar B 0 3 and tetrahedral P 0 4 units which are not joined together. Zinc occupies three crystallographically different point positions and is trigonal-bipyramidally, tetragonal-pyramidally or distorted tetrahedrally coordinated by oxygen.
