In the title compound, [Cu(CH3CN)(C14H12N2)2](BF4)2·2CH3CN, the CuII atom shows a distorted CuN5 square-pyramidal geometry with the acetonitrile N atom in an equatorial site, which differs substanti­ally from the distorted trigonal-bipyramidal arrangement usually observed for five-coordinate complexes of CuII with two phenanthroline-type ligands and one other ligand. The B atom of one of the BF4− anions is disordered over two sites in a 0.825 (2):0.175 (2) ratio. In the crystal, C—H⋯F hydrogen bonds help to establish the packing.
