More model informationCrystal System: Tetragonal
Crystal Class/Point Group (Hermann-Mauguin notation): -42m
Crystal Class/Point Group (Schönflies notation): D2d
Symmetry: 1-A4, 2A2, 2m
Name of Class: Tetragonal-scalenohedral
Notes: This class has a 4-fold rotoinversion axis that is perpendicular to 2 2-fold rotation axes. The 2 mirror planes a parallel to the and are at 45° to the 2-fold axes. Chalcopyrite and stannite are the only common minerals with crystals in this class.
