crystallographic databases are specifically built to store molecular and crystal structures details, e.g, CSDC database(Groom, Bruno et al. 2016) containing over one million structures from x-ray and neutron diffraction analyses and Crystallography Open DB(Grazulis, Daskevic et al. 2012) provide a huge amount of crystallographic information for the researcher and Open-access for collection of crystal structures of organic, inorganic, metal-organic compounds and minerals etc. We have collected 24 crystallographic databases, which is easily accessible by clicking the database name.
