Figure 1 ORTEP-3 view (Farrugia, 1997) of the FeF63− octahedron, the isolated water molecule and the Cu(H2O)4F+ square-based pyramid which is forming octahedra dimeric units when considering the very long Cu-O3 distance (2.715Å). Displacement ellipsoids are shown at the 50% probability level. Symmetry-equivalent F atoms in the FeF6 group are generated by (i) −x, −y, −z. Symmetry-equivalent atoms in the [Cu2(H2O)8HF2]3+ unit are generated by (iii) 1-x, 1-y, −z. |
