    Description / Table of Contents: Crystal and Molecular Structure of Di-μ-iodo-tetrakis[tris(phenylethynyl)phosphine]dicopperThe preparation and the properties of the title compound are described. The X-ray analysis has shown that the triclinic unit cell of the complex contains two dimeric molecules {[(C6H5—C≡C)3P]2CuI}2. Therein both Cu1 atoms are coordinated approximately tetrahedraly and linked by two iodine bridges. The bond lengths and angles as well as the vC≡C and δ31P NMR values are compared with those of uncoordinated P(C≡C-C6H5)3, used firstly as ligand.
    Notes: Darstellung und Eigenschaften der Titelverbindung werden beschrieben. Die Röntgenstrukturanalyse ergab, daß die trikline Elementarzelle des Komplexes zwei dimere Moleküle {[(C6H5—C≡C)3P]2CuI}2 enthält. Darin sind die beiden Cu1-Atome annähernd tetraedrisch koordiniert und durch zwei Iodbrücken verknüpft. Die Bindungslängen und -winkel sowie die vC≡C— und δ31P-NMR-Werte werden mit denen des unkoordinierten P(C≡C—C6H5)3 verglichen, das erstmals als Ligand verwendet wurde.
