Figure 1
The [NbOF5]2− anions, showing the elongated displacement ellipsoids of the Nb1 atoms when situated on the inversion centre [(a) for (I) and (c) for (II)] and the disordered displacement of the Nb1 atoms from the inversion centre [(b) for (I) and (d) for (II)]. Displacement ellipsoids are drawn at the 50% probability level. [Symmetry code: (i) −x, −y + 1, −z + 1, for (I); (i) −x + 2, −y, −z + 2, for (II).] |
