The title compound, [4′-(4-bromo-phenyl)-2,2′:6′, 2″-ter-pyri-dine]-chlorido(trifluoro-methane-sulfonato)-copper(II), [Cu(CF3O3S)Cl(C21H14BrN 3)], is a new copper complex containing a polypyridyl-based ligand. The CuII centre is five-coordinated in a square-pyramidal manner by one substituted 2,2′:6′,2″-ter-pyridine ligand, one chloride ligand and a coordinated trifluoro-methane-sulfonate anion. The Cu - N bond lengths differ by 0.1 A for the peripheral and central pyridine rings [2.032 (2) (mean) and 1.9345 (15) A, respectively]. The presence of the trifluoro-methane-sulfonate anion coordinated to the metal centre allows Br...F halogen-halogen inter-actions, giving rise to the formation of a dimer about an inversion centre. This work also demonstrates that the rigidity of the ligand allows the formation of other types of nonclassical inter-actions (C - H...Cl and C - H...O), yielding a three-dimensional network.
