title: Bis(di-2-pyridylmethane-diol-κN,O,N')copper(II) bis-(tetra-fluorido-borate) dihydrate.
abstract: The title complex, [Cu(C(11)H(10)N(2)O(2))(2)](BF(4))(2)·2H(2)O, was isolated as a dihydrate from a 1:2 molar mixture of copper(II) tetra-fluoridoborate hexa-hydrate 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 octa-hedral geometry by the so-called 'off-axis angle' distortion. The BF(4) (-) anion exhibits a two site disorder of the fluorine atoms [ratio 0.210 (8):0.790 (8)].
