Abstract
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'-dimeth-oxy-2,2'-bi-pyridine, C(12)H(12)N(2)O(2), is sixfold coordin-ated by the N atoms of the chelating bi-pyridine ligand, the N atoms of two aceto-nitrile mol-ecules, and two tri-fluoro-methane-sulfonate O atoms in a tetra-gonally distorted octa-hedral shape. The formation of polymeric chains [Cu(CH(3)CN)(2)(diOMe-bpy)(CF(3)SO(3))](+) (n) leaves voids for the non-coordinating tri-fluoro-methane-sulfonate anions that inter-act with the complex through weak hydrogen bonds. The presence of weakly coordinating ligands like aceto-nitrile and tri-fluoro-methane-sulfonate makes the title compound a convenient starting material for the synthesis of novel metal-organic frameworks.
