QM9 current DeepChem 3D structure archive
QM9 current DeepChem 3D structure archive; complete source artifact.
Processed copy of qm9_structures from the molecular datasets collection. Structures are canonicalized and validated; labels are never averaged or filled. Prefer the original source for citation.
Where the data comes from
Data quality
Grade: unmeasured (rough; rules on the hub page).
- info: computed. Label origin from the source's tags.
Modalities
Besides SMILES and labels:
| Modality | Where | Content |
|---|---|---|
| source files | files/qm9.tar.gz (53 MB) |
Original file, unchanged. No SMILES table was built from it. |
Files are copied unchanged from the original source:
from huggingface_hub import hf_hub_download
path = hf_hub_download("liuganghuggingface/moldata-qm9_structures", "files/qm9.tar.gz", repo_type="dataset")
Known issues
- DeepChem corrected formal-charge parsing in older SDF files in 2026. Preserve the archive and align records by molecule identifier.
