Solid angle data (G)a for selected alkyl-substituted tris(carbene)borate ligands in {NiNO}10 complexes.
| Ligand | Full ligand | Truncated ligandb |
|---|---|---|
| HB(MeBz)3−c | 36.9 | 37.0 |
| HB(CyCH2Bz)3− | 56.3 | 36.9 |
| PhB(CyCH2Im)3−c | 52.8 | 39.0 |
| HB(tBuIm)3− | 53.2 | 53.2 |
| Tp* | 37.0 | 37.0 |
| PhB(CH2PPh2)3− | 55.4 | 54.1 |
Solid angles expressed as percentage coverage of a sphere. The G values were calculated using a metal ligand distance of 2.28 Å.
Ligand was truncated at a radius of 4 Å from the metal center.
Average values for the four independent molecules in the asymmetric unit.
