In order to study the e ects of crystal structures on resolvability, a CSD (Cambridge Crystallographic Database) study has been carried out on 1-phenylethylammonium diastereomeric salt pairs with available crystal structures. The structures of the diastereomers of the salts are analyzed, compared and grouped. The structural features are set against the resolution results. The e ects of three types of structural features on the resolution e ciency are demonstrated.
