This paper describes the synthesis and structural characterization of two new one-dimensional coordination polymers involving 1,3-bis(4-pyridyl)propane ligand named {(μ-NCS)2[Cu(bpp)] ·dmf} n ( 1) and {[Cu(mebpy)(bpp)(dmso)](ClO4)2 ·dmso} n ( 2) (bpp = 1,3-bis(4-pyridyl)propane and mebpy = 4,4'-dimethyl-2,2'-bipyridine). These compounds were characterized by means of elemental analysis, thermal analysis (TG/DTA), vibrational spectroscopy (IR and Raman) and had their structures determined by single-crystal X-ray diffraction analysis. Compound 1 consists of CuN4 coordination spheres with bpp ligands in the unusual GG conformation coordinated in bridges between CuII centers to form a wavelike 1-D coordination polymer. On the other hand, in compound 2 the bpp ligand adopts the TT conformation in bridging mode extending the 1D cationic polymeric chain. [ABSTRACT FROM AUTHOR]

The complexes [Cu5(CN)5(5-ph-2,2′-bpy)3] n ( 1) and {Cu(SCN)(5-ph-2,2′-bpy)} n ( 2) were prepared by reaction of CuCl2 with different bridging ligands such as cyanide- or thiocyanate under hydrothermal conditions in the presence of 5-phenyl-2,2′-bipyridine (5-ph-2,2′-bpy). The copper ions are bridged by cyanide anions to form 1D ribbon with 26-membered {Cu10(CN)8} rings in complex 1, whereas the metal ions are bridged by thiocyanate anions to form a 1D chain in complex 2.
