cyberscience: extracting crystallography from Elsevier's Tetrahedron via CCDC

Regular readers will know of our Crystaleye repository where Nick Day’s robots have – quite legally – extracted ca 100,000 crystal structures from the Open AND closed literature. However it is not yet comprehensive as some publishers do not expose their data Openly but have a deposition arrangement with the Cambridge Crystallographic Data Centre (CCDC) [No formal relationship to us, although 100 metres away and built by the same architect]. So we are now looking to extract these structures into Crystaleye.
As I blogged recently (THANK YOU ELSEVIER!) Elsevier have no objection to the extraction of crystallographic data from their journals. The first journal I’m starting with is Tetrahedron [1]. Here I take you through the process from first the author’s point of view and then the reader’s/user’s. From the Guide for authors (and omitting large amounts of unexceptionable material) we have:

X-ray crystallographic data: Prior to submission of the manuscript, the author should deposit crystallographic data for organic and metalorganic structures with the Cambridge Crystallographic Data Centre. The data, without structure factors, should be sent by e-mail to deposit@ccdc.cam.ac.uk, as an ASCII file, preferably in CIF format. Hard copy data should be sent to CCDC, 12 Union Road, Cambridge CB2 1EZ. A checklist of data items for deposition can be obtained from the CCDC Home Page on the World Wide Web (External link http://www.ccdc.cam.ac.uk) or by e-mail to: fileserv@ccdc.cam.ac.uk, with the one-line message, send me checklist. The data will be acknowledged, within three working days, with one CCDC deposition number per structure deposited. These numbers should be included with the following standard text in the manuscript: Crystallographic data (excluding structure factors) for the structures in this paper have been deposited with the Cambridge Crystallographic Data Centre as supplementary publication nos. CCDC. Copies of the data can be obtained, free of charge, on application to CCDC, 12 Union Road, Cambridge CB2 1EZ, UK, (fax: +44-(0)1223-336033 or e-mail: deposit@ccdc.cam.ac.Uk). Deposited data may be accessed by the journal and checked as part of the refereeing process. If data are revised prior to publication, a replacement file should be sent to CCDC.

PMR: Relatively simple – if I want the crystallographic data from a structure it can be retrieved from CCDC. Let’s see it from the reader’s point of view. Although Tetrahedron is closed, there is a Free-to-view issue which includes:

Calix[4]azacrowns: self-assembly and effect of chain length and O-alkylation on their metal ion-binding properties
Pages 62-70
Issam Oueslati, Pierre Thuéry, Oleksandr Shkurenko, Kinga Suwinska, Jack M. Harrowfield, Rym Abidi and Jacques Vicens

PMR: Now all of you should be able to click along with me since the Full Text is Free-to-read… and we find towards the end…

5.3. X-ray crystal data for 1 and 4
Crystal data and refinement details for 1·CH3CN·CH3OH. C53H71N3O7, M=862.13, monoclinic, space group C2/c, a=35.499(1), b=11.8598(2), c=25.6668(8) Å, β=15.288(1), V=9770.5(4) Å3, Z=8, Dc=1.172 g cm−3, μ=0.077 mm−1, F(000)=3728. Refinement of 601 parameters on 6923 independent reflections out of 42440 measured reflections (Rint=0.037) led to R=0.081, wR=0.192, and S=1.13. Crystal data and refinement details for 4·CH3CN·CHCl3. C54H70Cl3N3O6, M=963.48, orthorhombic, space group Pna21, a=12.6378(2), b=33.1849(13), c=12.6464(5) Å, V=5303.7(3) Å3, Z=4, Dc=1.207 g cm−3, μ=0.223 mm−1, F(000)=2056. Refinement of 608 parameters on 7285 independent reflections out of 25830 measured reflections (Rint=0.054) led to R=0.056, wR=0.157, and S=1.07. Crystallographic data for the structures of 1 and 4 have been deposited with the Cambridge Crystallographic Data Centre as supplementary publication nos. CCDC 621387 and CCDC 621388. Copies of data can be obtained, free of charge, on application to CCDC, 12 Union Road, Cambridge CB2 1EZ, UK.

PMR: ( 1 and 4 signify compounds 1 and 4 in the main text  most authors and publishers use a unique numbering scheme within the paper.) So I can apply to CCDC for the structures which should be free. Will they be Open? Here’s what we have to do: On the Request Structure page:

Since 1994, under official deposition arrangements with a number of journals, the Cambridge Crystallographic Data Centre (CCDC) has provided copies of the supplementary data of individual published structures for bona fide research purposes. Data from before 1994 are currently only available from the distributed Cambridge Structural Database (CSD).
Supplementary data arriving at the CCDC electronically in CIF format whether as part of journal deposition arrangements or directly from individuals are held on trust in the CCDC Supplementary Data Archive on behalf of those journals and individuals. After publication, these data are converted into CSD entries by the addition of bibliographic and chemical text, chemical structural data, and the results of crystal structure validation.
In January 2002 CCDC provided a web form for data retrieval, which requires you to enter brief literature citation details and the CCDC Deposition Number (CCDCnnnnnn) which should appear in the paper.
This free service permits rapid access to supplementary CIF data for bona fide research purposes. The complete Cambridge Structural Database containing fully validated information may also be available within your institution or department.

PMR: and now the conditions…

Conditions of Use of CIFs provided from the CCDC CIF archive Individual CIF data sets are provided freely by the CCDC on the understanding that they are used for bona fide research purposes only. They may contain copyright material of the CCDC or of third parties, and may not be copied or further disseminated in any form, whether machine-readable or not, except for the purpose of generating routine backup copies on your local computer system.
If you agree to the foregoing terms and conditions then please click on the “Accept” button below. If you do not accept the foregoing terms and conditions you should not click on the “Accept” button but should click on the “Do NOT accept” button below or the “back” button on your browser.

PMR: This doesn’t look crystal clear. “They may contain copyright material of the CCDC or of third parties”. A very fuzzy statement. They may only be used for “bona fide research purposes”. This is an unclear phrase. “may not be copied or further disseminated in any form, whether machine-readable or not”. This is fairly clear. The user has very few rights if any. Anyway I “agree” the conditions for once and find the form:
