The central copper(II) atom of the title salt, {[Cu(CF(3)SO(3))(CH(3)CN)(2)(C(12)H(12)N(2)O(2))](CF(3)SO(3))}( n ) or [[Cu(CH(3)CN)(2)(diOMe-bpy)(CF(3)SO(3))](CF(3)SO(3))]( n ) where diOMe-bpy is 4,4′-dimeth­oxy-2,2′-bi­pyridine, C(12)H(12)N(2)O(2), is sixfold coordin­ated by the N atoms of the chelating bi­pyridine ligand, the N atoms of two aceto­nitrile mol­ecules, and two tri­fluoro­methane­sulfonate O atoms in a tetra­gonally distorted octa­hedral shape. The formation of polymeric chains [Cu(CH(3)CN)(2)(diOMe-bpy)(CF(3)SO(3))](+) ( n ) leaves voids for the non-coordinating tri­fluoro­methane­sulfonate anions that inter­act with the complex through weak hydrogen bonds. The presence of weakly coordinating ligands like aceto­nitrile and tri­fluoro­methane­sulfonate makes the title compound a convenient starting material for the synthesis of novel metal–organic frameworks.
