Acetonitrile-bis-(2-methyl-1,10-phenanthroline)copper(II) tetra-fluoridoborate.

In the title compound, [Cu(CH(3)CN)(C(13)H(10)N(2))(2)](BF(4))(2), the fivefold-coordinate Cu(II) atom is located on a twofold rotation axis, imposing twofold symmetry to the complete cation. The structure exhibits disorder of the anion, which was successfully refined using a two-site model with 0.810 (3):0.190 (3) occupancy. The methyl group of the acetonitrile ligand is likewise disordered, here about the twofold rotation axis in a 1:1 ratio.
