| Rotation | α | β | γ | Ref. |
|---|---|---|---|---|
| Rd | −79.1 | 32.1 | 75.6 | This work |
| −71.6 | 35.2 | 82.5 | 5 | |
| Rg(2)→g(1)† | 83.7° | 118.0° | 95.7° | This work |

†Rotation matrix between the principal axes of the g-tensors of spin 1 and spin 2. The angles are Euler angles defined in a left-handed coordinate system for counterclockwise rotations.
‡Angles between the corresponding x, y, and z axes (gi) of the g-tensor of Y· and the respective molecular axes of reduced Y122 from the x-ray structure of ref. 5.
