WebbIn crystallography, a Strukturbericht designation or Strukturbericht type is a system of detailed crystal structure classification by analogy to another known structure. The designations were intended to be comprehensive but are mainly used as supplement to space group crystal structures designations, especially historically.

WebbThat means: A monoclinic crystal with β= 90° is still monoclinic. The diffraction pattern from such a crystal will have monoclinic symmetry, even though the metric symmetry … WebbFIG. 1. Tetragonal I4/mmm structure crystal structure adopted by the Mn xGa system. It can be considered as being constructed from two MnGa (P4/mmm) cells stacked on top of each other, the 2a and 2b sites are equivalent and are occupied by gallium, while the 4d sites are occupied by manganese. In the end member of this series (Mn3Ga, I4/mmm), …

The structure is two-dimensional and consists of two Ti₂Cu sheets oriented in the (0, 0, 1) direction. Ti is bonded in a 4-coordinate geometry to four equivalent Cu atoms. All Ti–Cu bond lengths are 2.69 Å. Cu is bonded in a distorted body-centered cubic geometry to eight equivalent Ti atoms.
