 Title    Reaktionen von Cadmium-und Quecksilber(II)halogeniden und -pseudohalogeniden mit Kronenethern: Kristallstrukturen der Komplexe von Benzo-18-krone-6 mit CdX2 und HgX2 (X = CI, Br) und von Dibenzo-18-krone-6 mit Hg(CN)2 Reactions of Cadmium and Mercury(II) Halides and Pseudohalides with Crown Ethers: Crystal Structures of the Complexes of Benzo-18-crown-6 with CdX2 and HgX2 (X = Cl, Br) and of Dibenzo-18-crown-6 with Hg(CN)2  
 Abstract    The reactions of benzo-18-crown-6 with MeX2 (Me = Cd, Hg; X = Cl. Br), and of dibenzo-18-crown-6 with Hg(CN)2 afford the compounds [Me(benzo-18-crown-6)X2] (1-4) and [Hg(dibenzo-18-crown-6)(CN)2 (5), resp., the crystal structures of which were determined. They consist of isolated neutral molecules, the crystalline Cd complexes and 5 contain one molecule of water of crystallization per formula unit, which however is not coordinated to the metal atom. The metal atoms are coordinated by the six O atoms of the ligands and the two halide atoms, or the two CN groups for 5, resp., the coordination being more unsymmetrical for the benzo than for the dibenzo ligand.

 Title    Metallkomplexe mit 2,2'-Dipyridylamin als Liganden: Kristallstrukturen der Komplexe mit CdX2 (X = Cl, Br, I) und CuCN Metal Complexes with 2,2'-Dipyridylamine as Ligand: Crystal Structures o f the Com plexes with CdX2 (X = Cl, Br, I) and CuCN  
 Abstract    Reactions of 2,2'-dipyridylamine (dpyam) with cadmium halides yield crystals of [Cd(dpyam)(H20)C l2] (1), [Cd(dpyam)Br2] (2), and [Cd(dpyam)I2] (3). With CuCl2 and KCN a complex [C u(dpyam)C N ]H 20 (4) is obtained. Depending on the size of the halide ions the coordination changes from octahedral in 1 to trigonal bipyramidal in 2 and tetrahedral in 3. The coordination in 4 is trigonal. Due to the geometric strain imposed by the ligand all coordination polyhedra show significant distortions. 1 and 2 form dimers by halide bridges. With the excep­ tion of 3 all compounds form "supramolecular" structures via hydrogen bonds, e.g. chains or networks.
