Figure 6
The dependence of the separation between two disordered positions of the Rb atom on pressure in [Rb(18-crown-6)][SbCl₆]. The best fit approximation is made using the third-order function P = A + Bd + Cd² + Dd³ in pressure range 0–2.16 GPa with A, B, C and D coefficients of 1.095, −0.6621, 0.3268 and −0.0915, respectively. P = pressure and d = d(Rb–Rb) separation. Blue circles and red squares correspond to data in compression and decompression cycles, respectively.
