The title complex, [Cu(BF4)2(C7H16O2S2)2]n, is isostructural with the perchlorate analog [Li et al. (2005). Cryst. Growth Des. 5, 1919–1932], both having a double-bridging one-dimensional chain structure containing sixteen-membered macrocyclic units. Each Cu atom lies on a crystallographic inversion center [ABSTRACT FROM AUTHOR]
