catena-poly[[bis(hexafluoroacetylacetonato-kappa O-2,O ')zinc(II)]-mu-4,4 '-bipyridine-kappa N-2 : N ']

Abstract

The structure of the title compound, catena-poly[[bis-(1,1,1,5,5,5-hexafluoropentane-2,4-dionato-kappa(2)O,O')zinc(III)]-mu-4,4'-bipyridine-kappa(2)N: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.
