Abstract: 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 - bonding between pyridine rings, and are organized as chains running along [11]. The stabilization of this architecture of chains is associated with a number of weak C-HF hydrogen bonds.
