O–H and O–C distances of the model MOF containing NDC linker and sum of the vdW radii of the O, C, and H atoms.
| Dicarboxylate linker in the model MOFs | Distances at 0.0° B3LYP-D3 (Å) | Sum of vdW radiia (Å) | ||
|---|---|---|---|---|
| NDC | O–Hb | O–Cb | O–H | O–C |
| 1.935 | 2.714 | 3.120 | 3.569 | |
The vdW radii are from general AMBER force field (ref. 53).
Distance between the O atom of the carboxylate group and the H or C atom which is in the rotational group and closest to the O atom.
