Figure 1 The crystal structure of [Cu2(HF2)(H2O)8][AlF6](H2O)2 in polyhedral representation projected along [010]. Colour key: O atoms white, F atoms green, H atoms are grey, [CuO5F] octahedra are blue, [AlF6] octahedra are red. Displacement ellipsoids are given at the 74% probability level; H atoms are displayed as spheres of arbitrary radius. Hydrogen bonds are indicated with green lines. Note that for clarity only one of the disordered H atoms bonded to the F atom is shown. |
