Syntheses, Raman spectroscopy and crystal structures of alkali hexafluoridorhenates(IV) revisited
The A (2)[ReF(6)] (A = K, Rb and Cs) salts are isotypic and crystallize in the trigonal space group type P [Image: see text] m1, adopting the K(2)[GeF(6)] structure type. Common to all A (2)[ReF(6)] structures are slightly distorted octahedral [ReF(6)](2−) anions with an average Re—F bond length of...

| description | The A (2)[ReF(6)] (A = K, Rb and Cs) salts are isotypic and crystallize in the trigonal space group type P [Image: see text] m1, adopting the K(2)[GeF(6)] structure type. Common to all A (2)[ReF(6)] structures are slightly distorted octahedral [ReF(6)](2−) anions with an average Re—F bond length of 1.951 (8) Å. In those salts, symmetry lowering on the local [ReF(6)](2−) anions from O(h) (free anion) to D (3d) (solid-state structure) occur. The distortions of the [ReF(6)](2−) anions, as observed in their Raman spectra, are correlated to the size of the counter-cations. |
