The title compound, trans-[Cu(C5HF6O2)2(C12H10N2)2], consists of monomeric units built up by a copper metal ion (lying on a center of symmetry) octahedrally coordinated by one oxygen-chelating hexafluoroacetylacetonate (hfac) group, a nitrogen-bound 1-(2-pyridyl)-2-(4-pyridyl)ethylene (2,4-bpye) ligand, and their symmetry equivalents generated by the symmetry center at the metal site. The monomers interact with each other through ππ bonding between pyridine rings, and are organized as chains running along [111]. The stabilization of this architecture of chains is associated with a number of weak C–HF hydrogen bonds.
