[Cu(2)(HF(2))(H(2)O)(8)][FeF(6)]·2H(2)O.

ABSTRACT: The title compound, octaaqua-(hydrogenfluorido)dicopper(II) hexa-fluoridoferrate(III) dihydrate, was synthesized under hydro-thermal conditions. The Cu atom is coordinated by one F and five O atoms within a highly distorted octa-hedron, forming dimeric [Cu(2)(H(2)O)(8)HF(2)](3+) units by edge sharing. These units are hydrogen bonded to [FeF(6)](3-) anions and to an inter-stitial water mol-ecule. The former feature Fe(3+) on a special position (). The dimeric copper units are linked to adjacent dimers by F-H⋯F hydrogen bonds. Additional O-H⋯O and O-H⋯F hydrogen bonds help to consolidate the crystal packing.
