A few weeks ago we ran a small poll on how we should deal with inorganic molecules - not just simple sodium salts, but things like organoplatinums, and other compounds with dative bonds, unusual electronic states, etc. The results from you were clear, there was little interest in having a lot of our curation time spent on these. We will continue to collect structures from the source journals, and they will be in the full database, but we won't try and curate the structures, or display them in the interface. They will be appropriately flagged, and nothing will get lost. So there it is, democracy in action.
So for ChEMBL 16 expect fewer issues when you try and load our structures in your own pipelines and systems.
Thanks for all your input.
