Bis(di-2-pyridylmethanediol-³N,O,N')copper(II) bis(tetrafluoridoborate) dihydrate

K. L. Brown, G. Crundwell and B. L. Westcott

Abstract: The title complex, [Cu(C₁₁H₁₀N₂O₂)₂](BF₄)₂·2H₂O, was isolated as a dihydrate from a 1:2 molar mixture of copper(II) tetrafluoridoborate hexahydrate with di-2-pyridyl ketone in aqueous solution. The centrosymmetric complex cation is structurally similar to that found in previously reported salts and exhibits Cu-O bonds deviating by 25 degrees from an octahedral geometry by the so-called `off-axis angle' distortion. The BF₄^- anion exhibits a two site disorder of the fluorine atoms [ratio 0.210 (8):0.790 (8)].
