Abstract:The structure of the title compound, catena‐polybis(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—H⋯O and C—H⋯F hydrogen bonds.
