Access Structures

Access Structures is the web interface provided by the Cambridge Crystallographic Data Centre for searching and retrieving crystal structure data from the Cambridge Structural Database. The CSD is the world's repository for small-molecule organic and metal-organic crystal structures, containing over 1.2 million experimentally determined structures. Through this platform, researchers can search by chemical name, formula, author, or structural parameters, and retrieve detailed crystallographic data including atomic coordinates, unit cell parameters, and three-dimensional molecular visualizations. For researchers in crystallography, materials science, drug design, and solid-state chemistry, Access Structures provides essential data for understanding molecular geometry, intermolecular interactions, and solid-state packing arrangements.
