CrystalWorks: Search multiple crystallographic databases
CrystalWorks provides access to the wide range of crystallographic
structure data made available by the Chemical Database Service.
It improves and extends the capabilities of the predecessor CrystalWeb
The system is still in a state of active development so please provide
us with reports about errors and problems. All comments, suggestions
and general feedback are most welcome (firstname.lastname@example.org).
CrystalWorks can be accessed via the CDS/DL Homepage.
It is also available via the EPSRC funded national service now
operated by the Royal Society of Chemistry.
Access to CrystalWorks
You can reach CrystalWorks via the
link in the top pulldown menu on the CDS/DL homepage.
There is also a link to the RSC portal on the homepage.
You do no need a username for initial access to CrystalWorks.
You will see a wide selection of sample structures on entering the
Moreover full display and download functionality is available for this
However, you do need to login to be able to perform online
searching and access the full range of database entries.
You can login within CrystalWorks or via the CDS/DL Homepage prior to

A scrollable box gives summary details of the Hits List entries.
Simply click on an item to get fuller details display in the
Selected Entry area below the Hits List box.
Please note that molecular display facilities are provided by the JSmol
It works well with all modern web browsers (including those on tablet
and other mobile devices) supporting HTML.

There is a button linking to a variety of search forms for all
the crystallographic databases.
Another button (Litref option) accesses entries selected from the
Cambridge database by a prior ConQuest search.
Structures can also be selected by entering their collection code or using
a database entry browsing option.
Full database access and search options are available to registered
CDS users only.
There is also a button to access the CDS user login form.
Links & data aggregators
This sub-menu provides a link (where available) to the electronic
literature for the bibliographic reference associated with the
selected database entry.
It also links to the major data aggregator sites which
potentially have compound information for the various component
moieties identified as being present within the crystal structure.
When a link to the electronic literature is present within the
database this is given.
In other cases an attempt is made to resolve the link by generating an
appropriate query to the CrossRef website.
It is possible to modify the query if the initial CrossRef search fails.
Searching of the aggregator sites is done using IUPAC International
Chemical Identifier IUPAC International Chemical Identifier
Search buttons are provided labelled by chemical formula, and the
various sites are searched using InchI Keys.
The data aggregators currently accessed are ChemSpider, ChEBI, NIST
WebBook and the NCI/CADD Chemical Lookup Service,

via the "Links..." menu.
Coordinates format download
A wide variety of coordinate formats are available for download and
They are selected from a pulldown manu, and format conversion is
performed on the fly with results shown on screen in a display box.
There is then the option to download directly to the user's workstation.
Conversion to most of the crystallographic formats by the system is
performed using the Bedlam system which has been developed inhouse.
It is also the option of adding new one related to specific user applications.
In addition use is made of the OpenBabel system. Most OpenBabel
output formats are also available.
Further information on OpenBabel can be reached via the
Jmol structure display
