[Rdkit-discuss] valence problem

[Adrian J. <jas...@gm...>]

Hi all
I have a problem with generating molecule from smiles.

from rdkit import Chem
template = Chem.MolFromSmiles('F[P-](F)(F)(F)(F)F.CN(C)C(F)=[N+](C)C')

I got an error:
 Explicit valence for atom # 1 P, 7, is greater than permitted

But the SMILES for this structure should be valid.
I checked many web services and the structure is always the same
the CAS number for this structure is 164298-23-1

Can I skip checking the valence during generating mol from smiles?

regards
Adrian
