The commission maintains a dedicated website at aperiodic.iucr.org by joint effort of the SIG3 and CAC. CAC is the Commission on Aperiodic Crystals established in April 1991 by International Union of Crystallography (IUCr). SIG3 is the Special Interest Group on Aperiodic Crystals established in August 1998 by European Crystallographic Association (ECA).

The Commission on Biological Macromolecules was established at the Ottawa General Assembly in 1981.

In 1966 the Moscow General Assembly authorized the Executive Committee to proceed with the formation of a Commission on Crystal Growth.

To reflect the expansion of the scientific interests of the Commission into the field of materials research related to crystal growth, the name was changed to Commission on Crystal Growth and Characterization of Materials at the Ottawa General Assembly in 1981.
