There are 7 crystal systems in 3D, which directly connect to 32 point groups when adding mirror planes and inversion. The 7 crystal systems are: Cubic, Hexagonal, Tetragonal, Trigonal, Orthorhombic, Monoclinic, Triclinic.

WebNov 7, 2024 · Crystallographic Axes. The symmetry of the Tetragonal System requires a set of 3 axes with two of the axes equal in length and the third axis either longer or shorter than the other two. The three axes are mutually perpendicular to each other. The two axes, equal in length are labelled a1 and a2. WebThe unique symmetry operation in a monoclinicThe unique symmetry operation in a monoclinic system is 2/m – a twofold axis of rotation with a mirror plane. b is the rotation, while a and clie in the mirror plane.
