Acetonitrilebis(2,9-dimethylphenanthroline)copper(II) bis(tetrafluoridoborate) acetonitrile disolvate

S. P. Watton

Abstract: In the title compound, [Cu(CH₃CN)(C₁₄H₁₂N₂)₂](BF₄)₂·2CH₃CN, the Cu^II 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 Cu^II 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-HF hydrogen bonds help to establish the packing.
