 Title    (CuI)2Pi4* ein neues Phosphorpolymer in einer Kupferhalogenid-Matrix (CuI)2P 14: a Novel Phosphorus Polymer in a Copper Halide Matrix  
 Abstract    (CuI)2Pi4 is a new adduct of copper iodide to a neutral phosphorus polymer. It is obtained by reaction of Cul and Pred at 400 °C. The compound crystallizes monoclinically, space group P2,/c (No. 14), a = 9.919(2), b = 9.718(2), c = 16.478(3) Ä, ß = 105.71(1)°, V = 1529.0(7) A3, with Z = 4. The crystal structure was refined to R\ = 0.029 for 2680 reflections and 173 parameters. It contains a new polymeric phosphorus allotrope with the translational unit P^° consisting of experimentally unknown [PI2] groups which are linked by [P2] fragments. The phosphorus rods consist of five-and six-membered rings, and are coordinated only by copper atoms.

 Title    Die Kristallstruktur von Thiocyanato(2-dimethylaminoäthanolato)kupfer(II) The Crystal Structure of Thiocyanato(2-dimethylaminoethanalato)copper(II)  
 Abstract    The crystal structure of the title compound has been determined from three-dimensional X-ray diffractometer data. Crystals are monoclinic, space group P2i/c with 8 CU(C4HIONO)SCN units in a cell of dimensions a = 11.951(4), b = 8.954(3), c = 16.805(6) Ä, and ß = 107.5(1)°. The structure was refined by least squares techniques to a final discrepancy factor of 0.041 based on 2234 observed independent reflexions. The compound is polymeric with copper atoms alternately bridged by two oxygen atoms and two thiocyanato groups. The coordination geometry around each copper atom is distorted square pyramidal. The basal plane consists of the two bridging oxygen atoms (mean value Cu-O: 1.914(3) A), the amino nitrogen atom (mean value Cu—N: 2.035(3) A) and the nitrogen atom from the thiocyanato group (mean value Cu-N: 1.908(3) A) while the axial coordination site is occupied by a sulfur atom from a thiocyanato group (mean value Cu-S: 2.979(2) A) centrosymmetric to the first. The magnetic susceptibility of the compound shows a broad maximum at 200 K.
