Access WebCSD

WebCSD is the web interface to Cambridge Structural Database (CSD) without the need to install any software. Contains published crystallographic data on organic, organometallic, and metal complex structures whose 3D structures have been determined using X-ray diffraction or neutron diffraction.  Updated weeklyWebCSD is available to Stanford students, faculty, and staff.

Features of WebCSD

  • Substructure searching
  • Similarity searching (only available in WebCSD)
  • Text/numeric searching (journal reference, compound name, all text)
  • Reduced cell searching
  • Database browsing
  • Customizable 3D display using embedded viewer (Elemental by Dotmatrics) — no local software installation required. External viewers also supported.
