Hi Greg, I am using the latest stable RDKIT Q2-2009, and getting:
In [30]: mol =
> AllChem.MolFromSmiles('[Mg]c1ccc([se]1)-c1ccc(n1)-c1ccc([Mg])cc1')
> [15:14:49] Can't kekulize mol
>
I assume it is from the Mg radicals.
What I should see is something like:
http://www.chemicalize.org/?q=[Mg]c1ccc([se]1)-c1ccc(n1)-c1ccc([Mg])cc1
Is this supported?
