The structure of the title compound, catena-poly[[bis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato-κ2O,O′)zinc(III)]-μ-4,4′-bipyridine-κ2N:N′], [Zn(C5HF6O2)2(C10H8N2)]n, consists of polymeric chains, running in two perpendicular directions, organized as planes normal to the tetragonal axis. The elemental unit of the chains is the zinc(II) coordination polyhedron bisected by a twofold symmetry axis, and thus only half of the unit is independent. The octahedral coordination geometry of the metal centre is composed of two oxygen-chelating (symmetry-related) hexafluoroacetylacetonate groups and two translationally related 4,4′-bipyridine groups, which act as connecting agents in the polymer structure. The stabilization of this architecture of chains and planes is associated with a number of weak C–HO and C–HF hydrogen bonds.
