ConQuest is the primary program for searching and retrieving
information from the Cambridge Structural Database (CSD). ConQuest
provides a full range of text/numeric database search options, in
addition to more complex search functionality.

The ConQuest 1.18 is now available
Item added 20/12/14
The ConQuest 1.17 is now available

The ConQuest 1.16 Release Notes list the following enhancement
ConQuest searches can be restricted to noncentrosymmetric or
centrosymmetric space groups.
The former can be useful in the rare and explicable cases where the
presence of an inversion centre modifies the conformational
distribution of a molecule in a crystal structure.

CDS modifications to ConQuest literature linking added
Local modifications allowing literature links have been implemented
for the new release (see Item added 22/08/11).
But please note that the "LitRef" link has been removed from the CDS
homepage. Access to any selected ConQuest entries is still possible
using CystalWorks, however.

ConQuest is now available with the latest Cambridge Release
ConQuest 1.15 has been made available with the new Cambridge Release
Item added 22/08/11
Following the August Cambridge update we were made aware that the
"IUCr" and CrosssRef" buttons had reappeared in the Author/Journal
display page. These buttons did not function correctly and have been
removed. The "LitLink" button remains and can be used to access the
electronic literature for the selected structure entry. For
background details see the Items added 04/01/07 & 14/12/05.
Please note that users of the CrystalWorks web browser interface can
also access their selected (LitRef) entries via a button on the Top
Level Display Menu.
Item added 21/01/11
ConQuest is now available with the latest Cambridge Release
ConQuest 1.13 has been made available with the new Cambridge Release
There have been a number of modifications.
The following has been taken from material in the latest Cambridge
SMILES String export: Individual or hitlists of structures can now be
exported in SMILES format. The SMILES string and the REFCODE are both
exported for each entry.
Fuller details of new features of all CSD components are available.

menu bar at the head of this Newsfile for fuller information.

Fuller details of ConQuest are now available
The following has been extacted from material in the latest Cambridge
Release Notes relating to ConQuest 1.12.
It is now possible to restrict searches to the best representative of
The CSD can contain multiple determinations of the same crystal
structure, reporting improved structural models, or new experiments
performed at different temperatures, pressures, or using different
radiations. These multiple inclusions could introduce bias in
Searches can now be restricted to just the best representative of each
unique polymorph, thus eliminating hits from duplicate crystal
structures. Four best representative subsets are available based on
R-factor, the presence of hydrogens, room temperature and lowest

ConQuest 1.12 was included with the latest Cambridge Major Release.
Item added 12/12/08
ConQuest 1.11 was included with the latest Cambridge Major Release and
has a number of new features.
There is a new "All Text" tabbed view in the "View Results" window
where all textual information for the entry can be viewed. As well as
information that is available for all entries such as publication
details, chemical formula, unit cell details, supplementary
information such as melting points, crystal habit, crystallisation
solvent are also provided where available.
For details of other enhancements follow the link to the "Cambridge
Release Notes" given above.
Item added 04/01/07
The "IUCr" and "CrossRef" buttons have now been removed from
Author/Journal display option (see Item added 12/12/06).
Item added 12/12/06
The LitLink button now works for Author/Journal view option for
display Search Results for the new ConQuest release. See the Item
added 14/12/05 for details on how we have implemented use of LitLink
for ConQuest on the CDS server.
With ConQuest 1.9 you may also see buttons labelled "IUCr" and
"CrossRef" for electronic journal linking. The IUCr button is
equivalent to the "LitLink" button for our implementation. If you
click the "CrossRef" button you fire up a web browser window. This
will hang for a period and then give you a "Network Timeout" message.
Please avoid using this option.
We are currently in contact with Cambridge and hope to come up with a
means of removing the "CrossRef" and possible "IUCr" buttons for our

ConQuest 1.9 was included with the latest Cambridge Major Release and
has a number of new features. For full details of changed from version
1.8 follow the link to the CSD "Release Notes" given above.
We have added better links to the Cambridge User Guide & Tutorial
material (including that for ConQuest). These are now available under
the heading "Training Material" in the top pulldown menu on
the CDS webpages

We remind CDS users that LitLink (direct linking to the primary
electronic jounals) is available for the networked version of ConQuest
provided by the Service. You need a web browser on your local
workstation to use this facility. There is a "LitLink" button
available in the Author/Journal results window. When you click this
button you will be presented with details on how to access the related
* Retention of previously selected entries
* Option to display structures using Jmol
Reasonably good connectivity is required to access the networked
version of ConQuest. This is fine from most university sites. In our
experience access via dialup is not possible. Broadband access for
home working is good, but the 3-D display facilities may be annoyingly
slow. If you find this to be the case we suggest you consider using
the JMol display option mentioned above. Other display options (for
instance linking to Mercury mounted on your local workstation) are
also being considered.

ConQuest 1.8 was included with the latest Cambridge Major Release and
has a number of new features. For details follow the link to the CSD
"Release Notes" given above.
Item added 07/01/05
ConQuest 1.7 was included with the latest Cambridge Major Release and
has a number of new features:
* It is now possible to restrict space group searching to
chiral (Sohnke) Space Groups.
* MDL, MOL files can be read into ConQuest via "File, Read
* Refcode searching has been improved and can retrieve all
entries in a Refcode family.
