| Liganden: Synthese und Struktur von [{6,6'-(CH3CH2CH2C = C)2bpy}Cu(Cl)(^-Cl)]2 Metal Complexes of 6 ,6 '-Dialkynyl-Substituted 2,2'-Bipyridine Ligands: Synthesis and Structure of [{6 ,6 '-(C H 3 CH2CH2C = C)2bpy}Cu(Cl)(a-Cl)] 2 The bipyridyldiacetylene 6,6'-(C H 3CH2CH2C = C)2bpy (1) was prepared by palladium catalyzed C -C -cou p lin g reaction of 6,6'-dibromo-2,2'-bipyridine with pentyne. Reaction of 1 with anhydrous CuCl2 in acetonitrile gave the dimeric, chloro-bridged complex (1)C u(C1)(m-C1)2Cu(C1)(1) (2), which was characterized by X-ray crystallography. The copper atoms in 2 are square-pyramidally coordinated with normal in-plane C u -N and C u -C l bond distances and one longer, apical bond to the second bipyridyl nitrogen atom. The influence of steric hindrance o f the bipyridyl 6,6'-substituents on the structure o f the complex is discussed. | | | |
