The free Access Structures
service offers downloads in a CIF file format. A successful search (using either the CCDC number, DOI of the journal article, DOI of the CSD entry or CSD refcode) displays a summary page including a “Download” button to download the structure data in CIF format. Read and accept the conditions of use to activate the download feature. Once you complete this first time verification step, you may select the "Download" button to download the required CIF file(s).
