catena-Poly[silver-μ-(di-2-pyridyl ketone)-N,O:N',O] Tetrafluoroborate

The title complex, [Ag(C₁₁H₈N₂O)]⁺_n.n(BF₄)⁻, contains polymeric [silver(di-2-pyridyl ketone)]⁺_n zigzag chains, counterbalanced by BF₄⁻ anions. The Ag atoms reside on inversion centers, the di-2-pyridyl ketone ligands lie with their carbonyl groups along crystallographic twofold axes and the BF₄⁻ ions also reside on inversion centers (and are disordered). The AgN₂O₂ moiety is precisely planar, with Ag—N 2.180 (3) and Ag—O 2.552 (1) Å, and N—Ag—O 69.35 (9)°.
