CDS Overview • Grant funded by EPSRC • Service free of charge to users • Based at Daresbury Lab (STFC) • Present Service started 1993 • 3 Staff (April -> 2 staff) • Provide access to data, support and training • Currently 3,400+ users from 100+ sites
Database coverage • Structural Data • Synthetic Organic Chemistry • Procuring Chemical Compounds • Spectroscopy • Physical Chemistry • Links to primary electronic literature Databases removed May 2007 Databases removed May 2007
Crystallography Databases Cambridge Structural Database (CSD) Crystal structure data for ~436,000 organic and organo-metallic compounds Inorganic Crystal Structure Database (ICSD) Over100,000 inorganic structures – also includes minerals and (recently) metals & alloys entries. CrystMet Crystal structure data for over115,000 metals, alloys, intermetallics, etc.
Crystallography Access CSD X-Windows based graphical CSD Interface - ConQuest (click the chevron symbols to view a related Flash Movie clip) All Data Web access CrystalWeb
Crystallography Access • ICSD WWW-ICSD - Web based system for ICSD CrystalWeb-Web access to all crystal data • CrystMet CrystalWeb
Crystallography Utilities Crystallographic file format converters • Bedlamis a generalised format converter very similar to the widely used converter program, Babel, but handles crystallographic data better. • Babelremains the package of choice to handle formats for a whole range of molecular modelling packages. Babel and Bedlem are both used by CrystalWeb to provide a wide range of output formats. Display and Analysis packages • Mercury - The 3D molecular structure viewer designed for use with the Cambridge structural database (CSD). • VISTA – CSD package for statistical analysis of geometrical feature. • Crad-A crystal radial distribution calculation program.

Database coverage • Structural Data • Spectroscopy • Physical Chemistry • Links to primary electronic literature
SpecInfo From Chemical Concepts, contains spectral data sets with their associated structure connection tables. A variety of features are available within the program to help with spectrum prediction and searching. Spectroscopy The Spectroscopy databases are designed to aid the chemist in structure elucidation and spectral interpretation problems.

Physical Chemistry - Access DETHERM • Client/Server Version 2.1
Physical Chemistry – Client • Version 2.1 of the DETHERM Client was made available to CDS users in March 2006 and is now the only supported version. • Version 2.x (first introduced in November 2004) has a better look and feel than previous versions and a number of new features including improved integration with AspenPlus. • It support data export in IK-CAPE PPDX (Physical Property Data Exchange format).
