There are many problem with the COD. The main problem
being that with ~20.000 entries, it includes only 5% of the whole stuff
(should be >400.000 entries). But let it grow and improve...

Faster growing would be obtained if authors realize that
they do not violate any copyright by sending their CIFs not
only to ICSD and CCDC/CSD, but also to the COD. About
that copyright question, here is the official RSC policy:
>"The RSC has a non-exclusive licence from authors to publish CIFs in

About incommensurate structures, the best place is certainly
in a specialized database like :

The current COD tools stupidly remove from the raw CIFs
many lines that would be essential in special cases,
but useless in the general case.
