Term used by some authorities to refer to @S05983@ resulting from the arrangement of out-of-plane groups with respect to a plane (@C01058@ @C01062@ ). It is exemplified by the @A00511@ of (E)-cyclooctene (@C01057@ plane = double bond and attached atoms) or monosubstituted paracyclophane (@C01057@ plane = substituted ring). The configuration of molecular entities possessing planar @C01058@ is specified by the stereodescriptors $$R_{\text{p}}$$ and $$S_{\text{p}}$$ (or $$P$$ and $$M$$).
