Table 2. Comparison of 120, 250, and 293 K data sets.
| 120 K | 250 K | 293 K | |
|---|---|---|---|
| a, c (Å) | 18.960 (3), 13.642 (2) | 19.039 (9), 13.651 (7) | 19.210 (10), 13.567 (8) |
| Vol (Å3) | 4903.8 | 4948.6 | 5007.1 |
| % Vol change (w.r.t. 293 K) | 2.1 | 1.2 | 0.0 |
| R[F 2 > 2σ(F 2)], wR(F 2), S | 0.0525, 0.1401, 1.028 | 0.0386, 0.1078, 1.029 | 0.0586, 0.1617, 1.017 |
Data recorded on a second crystal selected from same batch. Crystal showed signs of degradation at higher temperatures, presumably due to solvent loss. Inspection of the crystal after 293 K data set showed fracturing within the crystal.
