• Strukturbericht symbols are a partly systematic method for specifying the structure of a crystal. Thus the A structures are supposed to be monatomic, B's are diatomic with equal numbers of atoms of each type, C's have a 2-1 abundance ratio, D0's are 3-1, etc. Unfortunately, this scheme breaks down as early as A15. Numbers were assigned in roughly the historical order of the study of the lattice.
• Barrett and Massalski give a table (p. 29) which gives the correspondence between the Strukturbericht types and the complexity of the crystal:
  
  

  Strukturbericht Designation	Crystal Type
  A	Elements
  B	AB compounds
  C	AB2 compounds
  D	AmBn compounds
  E, F, G, H ··· K	More complex compounds
  L	Alloys
  O	Organic compounds
  S	Silicates
