The title compound,
trans-[Cu(C
5HF
6O
2)
2(C
12H
10N
2)
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 π–π 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—H
F hydrogen bonds.

Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
