axial chirality

https://doi.org/10.1351/goldbook.A00547
Term used to refer to @S05983@ resulting from the non-planar arrangement of four groups in pairs about a @C01059@. It is exemplified by @A00238@
abC=C=Ccd
(or
abC=C=Cab
) and by the @A00511@ of ortho-substituted biphenyls. The @C01249@ in molecular entities possessing axial @C01058@ is specified by the stereodescriptors Ra and Sa (or by P or M).
