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. |
