Crystal Lattice Structures: Index by Strukturbericht Designation

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.
