    Description / Table of Contents: Crystal and Molecular Structure of CuBr · (C2H5)4P2 (Monoclinic Form)The crystal structure of the copper(I) complex CuBr · (C2H5)4P2 has been determined by X-ray structure analysis. The substance crystallizes monoclinic, space group C2h5-P21/n with a = 10.78, b = 15.74, c = 7.54 Å, β = 84.6° and 4 formula units in the unit cell. The structure was solved by conventional heavy atom methods and has been refined to a final R-value of 0.14. The structure is characterized by continous chains, the copper atoms are tetrahedrally coordinated and linked together by alternating double bridges of two bromine atoms and two biphosphine molecues, respectively.
    Notes: Die Kristallstruktur von Tetraäthylbiphosphin-Kupfer(I)-bromid, CuBr · (C2H5)4P2, wurde mit Hilfe einer Röntgenkristallstrukturanalyse bestimmt. Die Verbindung kristallisiert monoklin in der Raumgruppe C2h5-P21/n mit den Gitterkonstanten a = 10,78, b = 15,74, c = 7,54 Å, β = 84,6° und 4 Formeleinheiten pro Elementarzelle. Die Struktur wurde mit Hilfe der Schweratom-Methode gelöst und bis zu einem R-Wert von 0,14 verfeinert. Sie besteht aus unendlichen Ketten. Die Cu-Atome sind tetraedrisch koordiniert und über alternierende Doppelbrücken aus 2 Br-Atomen bzw. 2 Biphosphin-Molekülen verknüpft.
