The title compound, [Cu(C10H8N2)3](BF4)2, shows the expected Jahn-Teller distortion at the pseudo-octa-hedrally coordinated CuII atom. Each CuII complex cation is surrounded by six BF4 - anions and each anion by three cations with weak C - H⋯F hydrogen bonds between them. One of the two BF4 - anions exhibits a rotational disorder (0.6:0.4) around one of the B - F bonds. © International Union of Crystallography 2007.
