Hi Jean-Marc, I know you can draw them, but both SMILES and RDKit internally use two bonds (up/down) directions to assign the bond stereo, which means that there are not enough bonds to define both double bonds configuration and have the middle one undefined at the same time. ---- Pozdrawiam, | Best regards, Maciek Wójcikowski mac...@wojcikowski.pl
