These examples explain


A Chiral sulfoxids: define the stereo chemistry by the single bonds.
B Metal carbonyl complex
C Metal bonded to a p-orbital. Treat h complexes in a similar manner.
D Chiral allens: SciDex do not calculate the chirality of allens. If you want to register enantiomeric allens, you have to do:- use up and down bonds (only for your display, they are not analysed by SciDex )- give a UQ attribute to the molecule, e.g. "UQ +" or "UQ R"- set "ST chiral" to the molecule


E Axial chirality of biphenyls have to be defined by UQ and ST attributes, similar then in D.
