MedeA ICSD - A Reliable Source of High-Quality Crystal Structure Data

MedeA ®[1] ICSD offers experimental crystal structure information for non-organic compounds, including ceramics, minerals, and metallic systems. With MedeA ICSD (Inorganic Crystal Structure Database), you have access to the structure database most frequently cited in literature. [2]


MedeA ICSD is an indispensable resource for any solid-state materials research and engineering project.

Key Benefits

  • Speeds up your modeling projects by providing validated experimental crystal structures
  • Seamless integration with all MedeA modules

MedeA ICSD - Number of records by constituent count

Together with MedeA InfoMaticA, ICSD is the ideal starting point for any materials modeling project. With a few mouse clicks, search ICSD along with other MedeA databases, view search results in tables, sort by any type of available data, and visualize one or more chemical unit cells. Use as direct input for simulations, or as a building block for further editing and model construction.


  • Extensive coverage for inorganic crystal structures. Total Number of Records: 217,000
  • All entries include lattice parameters and atomic coordinates
  • 9,093 structure prototypes
  • Comprehensive data sets dating back to 1913

MedeA ICSD provides many essential properties for experimentally determined crystal structures, as well as meta data on experimental conditions such as temperature, pressure, etc.

Key Features

  • Integration with MedeA InfoMaticA provides fast, on-disk, cross-database search
  • Quick, efficient structure retrieval using an intuitive, menu-based query language
  • Regular database updates, along with MedeA updates
  • Compatible with all MedeA compute engines and MedeA property modules

‘ICSD is an indispensable source of information for chemists, physicists, crystallographers, mineralogists, and geologists teaching or doing research in the field of crystallography.’
