 Title    Kristallstruktur und hydrothermale Darstellung der Schichtverbindung B e2( P 0 4)(0 H )* 2 H 20 Crystal Structure and Hydrotherm al Synthesis of the Layered Com pound Be2 ( P 0 4 ) (0 H ) * 2 H 20  
 Abstract    Colourless monoclinic single crystals of B e2(P 0 4) (0 H) -2 H 20 (space group P 2 Jn) have been prepared under hydrothermal conditions in aqueous solution. Crystal data: a = 631.7(1), b = 1108.7(2), c = 812.7(2) pm, ß = 105.83(2)°, 910 unique reflections, 108 parameters, Rg = 0.0233. P is tetrahedrally coordinated by 4 oxygen atoms. Each of the two crystallographically unique Be atoms has two phosphate oxygen atoms, one water molecule, and one OH group as coordination partners. The tetrahedra share common vertices and build up a two-dim ensionally infinite pattern. The OH group links the two unique Be centered tetrahedra. Loss of water com m ences at 300 °C and is finished at 580 °C.

 Title    CuX (X = Br, I) Oligomers and Polymerie Chains in Tetramethylcyclotetra- arsoxane-Bridged Networks [Cu/iX/Jcjc/o-CCH^AsO)^] (n = 4, 6, 8)  
 Abstract    Open lamellar structures 2 [Cu-jLjcyc/o-tCH iA sO ^}?] (1) and 2 [{CuX(CuX • C H 3CN)2}{c>'c/o-(CH3 AsO)4}] [X = Br (2), X = 1 (3)] may be prepared by self-assembly from CuX and methylcycloarsoxane (CH3AsO)" in acetonitrile solution at 100-130 °C. W hereas 1 contains CU4I4 oligomers consisting of three fused (C ul)2 rings, 2 and 3 exhibit infinite J. [CuX] single chains. An acceleration in the rate of heating between 20
