Figure 9
Variation in (a) the unit-cell volume (•) and (b) the a (□) and c (filled □) axis lengths over the temperature range 300→200 K for form I. Error bars (where visible) are drawn at ±(3 × s.u.). The clear discontinuities in the axis lengths correspond to the phase transformation from the `high-temperature' TFDIB framework to the `low-temperature' framework. |
