abstract= {This is an archive from PubChem, https://pubchem.ncbi.nlm.nih.gov/

This archive contains only the PubChem3D project, with 10 diverse conformers per compound, in SDF format.  This corresponds to the backend FTP folder `ftp.ncbi.nlm.nih.gov/pubchem/Compound_3D/10_conf_per_cmpd/SDF`.  There are companion torrents for the [ASN.1](https://storewhatever.cloud/details/da0f75a319889459290b606c417529d540bbce25) and [XML](https://storewhatever.cloud/details/3f14fd37df52729b3e7975b0339dce64e46e44c6) formatted data.

From the README, present in the [base torrent for PubChem3D](https://storewhatever.cloud/details/fc044237ff0c901ce32db5d51a71a71df8b9f07f):

The PubChem3D project computes [1-7] a theoretical 3-D description of
PubChem Compound records.  For more details, read the release notes:

The data contained here consists of a theoretical 3D description of PubChem           
Compound records computed[1-3] using the MMFF94s force field[4-5] without             
coulombic terms, including MMFF charges[6-7].  Each provided theoretical 3D
conformer is not a stationary point on the hyper-potential surface (i.e., is
not at a minimum energy).  Rather, the theoretical 3D description is a low
energy conformer selected from a conformer model (a theoretical description
of the conformational flexibility of a chemical structure consisting of  
multiple 3D representations or poses sampled using an RMSD {root mean squared
distance} threshold) describing energetically-accessible and (potentially)  
biologically relevant conformations of a chemical structure.
