Metal–ligand stability constants determined from least square fits to spectroscopic titration data using HyperQuad22 (T = 25 °C).
| Ligand | Metal salt | Solvent | log β1:1 | SDa | log β1:2 | SDa |
|---|---|---|---|---|---|---|
| 1 | Eu(NO3)3 | H2O | 7.05 | 0.034 | 12.37 | 0.142 |
| 1 | Tb(NO3)3 | H2O | 6.58 | 0.026 | 12.01 | 0.079 |
Standard deviation determined by the fitting process.
