Search Known Small Molecules

Structural chemists search known small molecules with CSD-Core.

CSD-Core provides essential search, visualisation and analysis features to deliver knowledge from the Cambridge Structural Database (CSD) with powerful 2D/3D search, extensive geometry analysis tools, intermolecular interaction analysis, high impact graphics and connectivity via the CSD Python API.

One-click generation of high-quality structure representations are available for effective scientific communication including POV-Ray graphics rendering, videos and even 3D printing.


Find structures with WebCSD

Cross-platform web-based structure retrieval to support your research, education or peer review.

Search with ConQuest

Answer very specific structure questions on your desktop using highly flexible 3D searching of the CSD and local in-house databases. Quickly identify structures based on a wide range of properties. Use interaction and structure-property knowledge to drive design decisions.

Visualise and analyse in Mercury

Represent molecular conformations, crystal structures, crystallographic planes and simulated morphologies with high quality graphics and videos. 3D print your molecules and structures.

Investigate conformations using Mogul

Harness the millions of chemically classified bond lengths, angles, torsion angles, and ring conformations in the CSD to obtain precise information on preferred molecular geometries.

Investigate interactions with IsoStar

Use the wealth of structural information available in the CSD to investigate the probability and characteristics of intermolecular interactions between pairs of chemical functional groups.

Connect with the CSD Python API

Create tailored scripts using the whole spectrum of CSD functionality to answer your targeted research questions. Integrate access to crystal data and CSD functions seamlessly with 3rd party software.
