Abstract Analysis of the geometrical parameters in crystal structures of square‐planar copper( II ) complexes from the CSD shows that the short noncovalent copper( II )−phenyl carbon distances are a consequence of the interaction between the phenyl ring and the chelate ring with delocalized π‐bonds. The data show a correlation between the distances between the centers of the chelate and phenyl rings and the copper( II )−carbon distances, as well as a mutual slipped‐parallel orientation of the phenyl and chelate rings.
