Rdkit explicit valence for atom
WebJul 12, 2014 · Atom no. 7 is a neutral nitrogen and it has 4 bonds. It is possible that you could silence RDKit in some way and force it to produce some answer, but I think you … WebSince, we did not explicitly designate a bond between the two atoms RDKit assumed we dont care if the bond is a single bond ( -) OR (,) an aromatic bond (: ), hence the characters between our atoms. Bond types can also be searched with characters for single ( - ), double ( = ), triple ( # ), aromatic (: ), ring bond ( @ ), or any ( ~ ).

WebSep 1, 2024 · This is the approach taken in the RDKit. Instead of using patterns to match known aromatic systems, the aromaticity perception code in the RDKit uses a set of rules. The rules are relatively straightforward. Aromaticity is a property of atoms and bonds in rings. An aromatic bond must be between aromatic atoms, but a bond between aromatic … WebOct 29, 2009 · Re: [Rdkit-discuss] Explicit valence for atom # 2 N greater than permitted.

WebJan 24, 2024 · Explicit valence for atom # 9 N, 4, is greater than permitted. This is because of the co-ordinate bond present in the molecule which RdKit doesn't support. RdKit will treat it as a single bond which will raise the valency of both the Nitrogen atoms to 4 and hence an invalid molecule. Here's the same molecule generated from other sources:
