Square‐planar complexes with achiral and chiral ligands have been enumerated exhaustively under the point‐group D 4 h and under the symmetry group S [4] of degree 4, where they have been classified in terms of their symmetries and permutabilities. Thereby, their stereochemical properties and relationships have been discussed in detail. In particular, equivalency under point‐group symmetry ( e.g. , enantiomeric relationships for chiral complexes and prochirality for achiral complexes) and that under permutation‐group symmetry ( e.g. , proper and improper permutations, stereogenic and astereogenic groups, and enantiostereogenic and diastereogenic groups) have been characterized to give a systematic format for stereochemistry and stereoisomerism.
