Structure and Properties of One‐dimensional Homometallic Complexes [Cu5(CN)5(5‐ph‐2,2′‐bpy)3]n and [Cu(SCN)(5‐ph‐2,2′‐bpy)]n (5‐ph‐2,2′‐bpy = 5‐Phenyl‐2,2′‐bipyridine)

Abstract The complexes [Cu 5 (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 CuCl 2 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 {Cu 10 (CN) 8 } rings in complex 1 , whereas the metal ions are bridged by thiocyanate anions to form a 1D chain in complex 2 .
