Volume 43 of Group III deals with crystallographic data of both intermetallic and classical inorganic compounds, thus forming an update of the former Landolt-Börnstein volumes III/6 (Structure Data of Elements and Intermetallic Phases) and III/7 (Crystal Structure Data of Inorganic Compounds). It does not include compounds that contain C-H bonds.

Moreover, in contrast to the earlier edition the present volume presents the data in a different, more modern arrangement - known crystal structures are combined in groups according to their type of structure; each structure type is therefore represented by a complete set of crystallographic data holding for all isotypic structures, with the data comprising space group, cell parameters and atom coordinates. Remarks, descriptions and figures are provided where necessary.

The present subvolume A 4, which utilizes the databases TYPIX and Pauling File, forms the fourth contribution to volume 43, which is going to be published ina series of subvolumes. Subvolumes A 1 - A 3 are already available.
