title: catena-Poly[[copper(II)-bis-[μ-bis-(pyridin-3-yl)methanone-κN:N']] bis-(tetra-fluorido-borate)].
abstract: In the title complex, {[Cu(C(11)H(8)N(2)O)(2)](BF(4))(2)}(n), the Cu(II) ion is situated on an inversion centre and adopts an N(4)F(2) octa-hedral coordination geometry with four N atoms from four different bis-(pyridin-3-yl)methanone ligands at the equatorial sites and two independent tetra-fluoridoborate anions weakly bonded at the axial sites via two F atoms [Cu⋯F = 2.613 (3) Å]. Chains with the bridging ligands are formed along the a axis. C-H⋯F inter-actions stabilize the structure. C-O⋯π inter-actions also occur.
