Abstract
Nine new cobalt fluorophosphates frameworks have been synthesised hydrothermally in a fluoride-rich medium, through the use of CoF(3) and HPF(6) as reactants in combination with Group I/II metal hydroxides and organic cations as templating species. Products have been structurally characterised using single crystal X-ray diffraction. Reaction in fluoride-rich conditions produces chain, layer and three dimensional framework structures containing new and unusual structural features based on the linking of PO(3)F, PO(2)(OH,F)(2) and Co(O,F)(n) polyhedra (n = 5-6) including μ(2), μ(3) and μ(4) bridging fluoride. Structures exhibiting inter-layer spaces and channels frequently have these lined by terminal fluoride anions of the PO(3)F, PO(2)(OH,F)(2) and Co(O,F)(n) polyhedra.
