Table A5.7.1.1 contains the request list for Acta Crystallographica Section C as given in the 2005 Notes for Authors. This list is appropriate for a single-crystal X-ray diffraction study and gives all the data items that are displayed in an article if they are present in the CIF. In principle, a smaller set of mandatory data items could be supplied as a separate request list. However, certain items may be considered mandatory or not depending on the nature of the study and on the presence of other data items in the CIF, so checking for mandatory items is performed through higher-level algorithmic checks during the pre-submission validation stage.
