Source: Landolt-Börnstein, New Series Volume: III/7d2 Page: 1-327 Year: 1980 ISBN: 3-540-10147-0 ISBN: 978-3-540-10147-5 Internet Resource: DOI:10.1007/b19979 RefComment: 23 figs., XXV, Hardcover Abstract: Volume III/7 contains structure data on those compounds which contain at least one of the elements F, Cl, Br, I, O, N, and P and cannot be called "organic". The structure data of the remaining inorganic compounds and the elements are dealt with in volumes III/6 and III/14, while the organic compounds are treated in volumes III/5 and III/10. The systematic arrange-ment is based on the anions ordered according to "key elements", since this system allows the arrangement of the crystal structure data in such a way that both chemical and crystallographical relationships can be recognized. Structure data are compiled as completely as possible for all inorganic substances, where crystal structures have been examined by means of X-ray, neutron, and electron diffraction,and for which at least the lattice constants have been determined.
