2. • Introduction:
• Crystallography is the study of Crystals.
• Crystallography, is the study of chemical structure of solid materials, through the
spatial arrangement of its atoms or ions in unit cells, the bonds that are formed.
The data obtained is then used to predict the synthesis, reactions, decomposition
of the material, its physical properties applications.
• Why look for free resources?
• Commercial sources for crystallography data are easier to use. But with a little
planning free sources can be searched to get a similar output?
• All crystallography databases get their data from published primary literature. So,
it is NOT imperative that we go to these databases exclusively. The advantage is
that data derived from the primary resources (journals) is arranged in some
logical way to be able to understand it better
3. Introduction…contd
• What is Crystallography, and why is it needed?
• Please Read the Introduction
• https://www.xtal.iqfr.csic.es/Cristalografia/index-en.html
4. • Before I go to the actual databases, I would like you to look at what
the Benedictine University library catalog offers in terms of Online
avaialibility.

from point to point groups, to magnetic space groups. (Free)
• http://www.cryst.ehu.es/
• Database of Zeolite structures (Free) SPECIALIZED

7. PUBCHEM
• This database is the best so far.
• PubChem is put out by the National Library of Medicine under NIH.
• PubChem
• The world's largest collection of freely accessible chemical
information. Search chemicals by name, molecular formula, structure,
and other identifiers. Find chemical and physical properties, biological
activities, safety and toxicity information, patents, literature citations
and more.
• Access PubChem through
• www.ben.edu/Library, click on Databases and go to P for PubChem
.
8. PubChem search – I am using the same
example of Ibuprofen throughout
10. Clicking on Ibuprofen in the previous slide will give you this screen. Click Spectral
Information on the right-hand side. ( #4 is Spectral Information). Besides, there is lot
of info on the structure properties etc. on the Right-hand side
11. Spectra. You will see the different types of spectra
depending on the spectroscopic instrument used.
13. Explanation of Spectra-1H-NMR
• Principles of NMR: How to Read Spectra and Couplings
• How to calculate coupling constants
• 1H NMR Spectrum (1D, 500 MHz, CDCl3
• , experimental) (HMDB0001925)
14. •ChemSpider
• Linking from CHEMSPIDER To Crystallography database
• CHEMSPIDER is put out by the Royal Society of Chemistry. It is a free database
and is similar to SciFinder-n
• http://www.chemspider.com/
• OR from https://www.ben.edu/library/index.cfm
• Scroll to the Cs. Advantage of going through ben.edu library is that all full text
articles that will appear in the search will be available for free (we have a
subscription) or ILL.
• An actual search for spectral data follows showing different screen shots.
18. There will be 3 records Click on the first
record. Click on Details
19. • Take note of these: SMILES, InChl. If you have these you can enter these when
searching the Crystallography Databases
Systematic Name, Synonym, Trade Name, Registry Number,
SMILES, InChI or CSID
Systematic names
1,2-dihydroxybenzene
Synonyms
AIBN
Trade names
Aspirin
Registry numbers
7732-18-5
SMILES
O=C(OCC)C
InChl
InChI=1/CH4/h1H4
20. • If you scroll down slide 8, you will see headers for
• Names, Names
• Properties
• Searches
• Spectra
• Vendors
• Articles
• More
• If you click on MORE you will see access to one of the free crystallography
databases. This site is explained in detail later.
• The spectra by different spectroscopic methods is available.
21.
22. •In the Introduction I said that all
databases for crystallography curate the
material data from SciFinder-n or other
research systems.
•Now we will address how to search
SciFinder-n for crystallography data.
23. SciFinder-n searches
• SciFinder-n is the premier indexing and abstracting service of the
American Chemical Society. We have a subscription. Access through
the Benedictine University Library Portal at
www.ben.edu/library/databases. Scroll down to the Ss. Click on either
choice and follow screen prompts.
29. Other ways to search
SciFinder-n
• You can start with
Reference Topic and enter
a text query using a CAS
Registry Number AND
“Spectra”. If you don't
already have an RN you
can use a chemical name,
but this is less precise.
30. • I am going to concentrate on Four free Databases. The last two by

32. From the right-hand side click on search, and put in the SMILES configuration
33.
34.
35. • You will notice that most files are in .CIF OR .Hkl format.
• That means you need to download the software that lets you open these
files?the software
• Any word file will open the .CIF file. But if you want to make changes then you
need to download the software explained below.
• CIF (Crystallographic Information Framework)
• The International Union of Crystallography is the sponsor of the Crystallographic
Information Framework, a standard for information interchange in
crystallography.
36.
37. • I clicked on the first entry which is highlighted in the previous slide. You are going
to scroll down and see what you want? Save file…remember where it is?
38. • Open AVOGADRO. Click on file – Open Recent
• You should see your file. In the example 1100123.cif
