Abstract

In the title complex, {[Cu(C11H8N2O)2](BF4)2}n, the CuII ion is situated on an inversion centre and adopts an N4F2 octahedral coordination geometry with four N atoms from four different bis(pyridin-3-yl)methanone ligands at the equatorial sites and two independent tetrafluoridoborate 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 interactions stabilize the structure. C—O⋯π interactions also occur.
