1,1,1,5,5,5-Hexafluoro-2,4-dimethoxypentane-2,4-diol

Abstract

The title compound, C7H10F6O4, was isolated as an unexpected product from a reaction of tantalum(V) methoxide with hexafluoroacetylacetone in a methanol solution. The asymmetric unit consists of one half-molecule with the middle C atom lying on a twofold axis. The crystal structure is stabilized by O—H...O and an array of C—H...F hydrogen-bonding interactions. These interactions link the molecules into a stable supramolecular three-dimensional network. The molecules pack in a ribbon-like form in the ac plane as a result of these interactions.
