Strukturbericht designation#B-compounds

{{Short description|System of detailed crystal structure classification}}

In 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.{{cite web|url=http://aflowlib.duke.edu/users/egossett/lattice/struk/index.html|title=Index by Strukturbericht Designation|publisher=US Naval Laboratory Center for Materials Physics and Technology|date=1 Sep 1995|access-date=6 Apr 2019|archive-date=12 September 2019|archive-url=https://web.archive.org/web/20190912194828/http://aflowlib.duke.edu/users/egossett/lattice/struk/index.html|url-status=dead}}{{cite journal|last1=Mehl|first1=Michael J.|last2=Hicks|first2=David|last3=Toher|first3=Cormac|last4=Levy|first4=Ohad|last5=Hanson|first5=Robert M.|last6=Hart|first6=Gus|last7=Curtarolo|first7=Stefano|title=The AFLOW Library of Crystallographic Prototypes: Part 1|journal=Computational Materials Science|volume=136|year=2017|pages=S1–S828|issn=0927-0256|doi=10.1016/j.commatsci.2017.01.017|arxiv=1806.07864|s2cid=119490841 }} Each Strukturbericht designation is described by a single space group, but the designation includes additional information about the positions of the individual atoms, rather than just the symmetry of the crystal structure. While Strukturbericht symbols exist for many of the earliest observed and most common crystal structures, the system is not comprehensive, and is no longer being updated. Modern databases such as Inorganic Crystal Structure Database index thousands of structure types directly by the prototype compound (i.e. "the NaCl structure" instead of "the B1 structure").{{cite journal | last1=Allmann | first1=Rudolf | last2=Hinek | first2=Roland | title=The introduction of structure types into the Inorganic Crystal Structure Database ICSD | journal=Acta Crystallographica Section A | publisher=International Union of Crystallography (IUCr) | volume=63 | issue=5 | date=2007-08-17 | issn=0108-7673 | pmc=2525864| doi=10.1107/s0108767307038081 | pages=412–417| pmid=17703075 | bibcode=2007AcCrA..63..412A | doi-access=free }} These are essentially equivalent to the old Stukturbericht designations.

History

The designations were established by the journal Zeitschrift für Kristallographie – Crystalline Materials, which published its first round of supplemental reviews under the name Strukturbericht from 1913-1928.{{cite journal|last1=Bragg|first1=W. L.|author-link1=Lawrence Bragg|title=Strukturbericht, 1913–1928|journal=Nature|volume=128|issue=3230|year=1931|pages=511–512|issn=0028-0836|doi=10.1038/128511a0|bibcode=1931Natur.128..511B|s2cid=4079798}} These reports were collected into a book published in 1931 by Paul Peter Ewald and Carl Hermann which became Volume 1 of Strukturbericht.{{cite book|last1=Ewald|first1=Paul Peter|last2=Hermann|first2=C.|title= Zeitschrift für Kristallographie, Kristallgeometrie, Kristallphysik, Kristallchemie|publisher=Leipzig: Akademische Verlagsgesellschaft m.b.H.|year=1931}} While the series was continued after the war under the name Structure reports, which was published through 1990,{{cite web|url=https://www.iucr.org/publications/other/structure-reports|title=International Union of Crystallography: Structure reports|access-date=6 Apr 2019}} the series stopped generating new symbols. Instead, some new additional designations were given in books by Smithels,{{cite book|first=Colin J |last=Smithells|title=Metals reference book|year=1949|edition=2nd|publisher=Interscience Publishers|location=New York|oclc=568858}} and Pearson.{{cite book | last=Pearson | first=W. B. | title=A handbook of lattice spacings and structures of metals and alloys | publisher=Pergamon Press | location=Oxford | year=1964 | isbn=978-1-4832-1318-7 | oclc=883896503 |doi=10.1016/C2013-0-08243-6| s2cid=239866683 }}

For the first volume, the designation consisted of a capital letter (A,B,C,D,E,F,G,H,L,M,O) specifying a broad category of compounds, and then a number to specify a particular crystal structure. In the second volume, subscript numbers were added, some early symbols were modified (e.g. what was initially D1 became D01, noted in the tables below as "D1 → D01"), and the categories were modified (types I,K,S were added). In the third volume, the class I was renamed J. Later designations began to use a lower case letter in subscripts as well.{{cite journal | last=Mehl | first=Michael J. | title=A Brief History of Strukturbericht Symbols and Other Crystallographic Classification Schemes | journal=Journal of Physics: Conference Series | publisher=IOP Publishing | volume=1290 | year=2019 | issue=1 | issn=1742-6588 | doi=10.1088/1742-6596/1290/1/012016 | page=012016| bibcode=2019JPhCS1290a2016M |doi-access=free}}
