| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| S°gas | 330.3 ± 3.8 | J/mol*K | N/A | Kabo G.J., 1995 | This value was calculated using the enthalpy of sublimation derived from effusion measurements. Other value, S(298.15 K)=336.2(3.4) J/mol*K, was calculated for enthalpy of sublimation determined calorimetrically. |
