Di-μ-chlorido-bis­[(2,2′:6′,2′′-terpyridine-κ(3) N,N′,N′′)copper(II)] bis­(tri­fluoro­methane­sulfonate)

In the centrosymmetric title complex, [Cu(2)Cl(2)(C(15)H(11)N(3))(2)](CF(3)O(3)S)(2), the Cu(II) metal center is fivefold coordinated by two chloride ions and three nitro­gen atoms of the terpyridine ligand in a distorted square-pyramidal geometry; two tri­fluoro­methane­sulfonate ions complete the outer coordination sphere. π–π stacking inter­actions between the pyridyl rings in adjacent mol­ecules contribute to the alignment of the complexes in columns along the a-axis. This structure represents the first example of a binuclear dication of formula [Cu(terpy)(2)Cl(2)](2+) with tri­fluoro­methane­sulfonate as counter-ions. [Image: see text]
