Database of Ionic Radii


Welcome to the database of ionic radii. The following web interface allows listing and comparison of ionic and crystal radii with different coordination and charge states.

Suggestions as to how the scope and content of the database can be extended are gratefully received.

The data contained in the database was taken from: R.D. Shannon, "Revised Effective Ionic Radii and Systematic Studies of Interatomic Distances in Halides and Chalcogenides", Acta Cryst. A32 751-767 (1976).

Although every effort has been made to ensure that the data is correct we take no responsibility for problems arising from errors contained in the database.
