|---|---|---|---|
| 56.319 | 298.15 | Van Miltenburg and Verdonk, 1991 | T = 5 to 370 K. There is an extended solid-to-solid transition between 260 and 309 K, of two regions, between 260-290 and 290-309 K.; DH |
| 35.9 | 250. | Loyzance, Rey-Lafon, et al., 1978 | T = 4.2 to 300 K. Data given graphically and estimated from graph. Transition at 308 K makes heat capacity at 298 K anomalous.; DH |
