[Chimera-users] Tetrahedral Sulphide bonds

[Elaine Meng]

Dear Yoga,
That is not really a Chimera question… maybe you can try searching some structure databases:

RCSB PDB search
<http://www.rcsb.org/pdb/secondary.do?p=v2/secondary/search.jsp#search_advanced-search>

There is also the Cambridge Structural Database for small molecules.
<https://www.ccdc.cam.ac.uk/>

Good luck,
Elaine
