Di-μ-chlorido-bis-[(2,2':6',2''-terpyridine-κ ,','')copper(II)] bis-(tri-fluoro-methane-sulfonate).

In the centrosymmetric title complex, [CuCl(CHN)](CFOS), the Cu metal center is fivefold coordinated by two chloride ions and three nitro-gen atoms of the terpyridine ligand in a distorted square-pyramidal geometry; two tri-fluoro-methane-sulfonate ions complete the outer coordination sphere. stacking inter-actions between the pyridyl rings in adjacent mol-ecules contribute to the alignment of the complexes in columns along the -axis. This structure represents the first example of a binuclear dication of formula [Cu(terpy)Cl] with tri-fluoro-methane-sulfonate as counter-ions.
