I've been using RDKit for depicting sets of ligands from SMILES, which has been great.
I'd like to add some bidentate and tridentate ligands. Let's stick to bipyridine at first (see image) I have the appropriate SMILES, leaving * as part of a 5 atom ring involving the nitrogen atoms (and sanitize = False) C12=CC=CC=[N]1[*][N]3=C2C=CC=C3 The resulting depiction is great .. except I'd like to add the attachment "squiggles" across the N-* bonds. I see there are DrawAttachmentLine and DrawWavyLine methods, but I'd need to get the positions of the N and * atoms. What's the best way to do that and / or automate adding wavy lines across arbitrary bonds? Thanks, -Geoff
