title: Acetonitrilebis(2,9-dimethylphenanthroline)copper(II) bis(tetrafluoridoborate) acetonitrile disolvate.
abstract: In the title compound, [Cu(CH(3)CN)(C(14)H(12)N(2))(2)](BF(4))(2)·2CH(3)CN, the Cu(II) atom shows a distorted CuN(5) square-pyramidal geometry with the acetonitrile N atom in an equatorial site, which differs substanti-ally from the distorted trigonal-bipyramidal arrangement usually observed for five-coordinate complexes of Cu(II) with two phenanthroline-type ligands and one other ligand. The B atom of one of the BF(4) (-) 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.
