The association meets annually in July and has several interest groups dealing with specific aspects of crystallography, including fiber diffraction, neutron scattering and powder diffraction.

A quarterly magazine, called ACA RefleXions, is published in addition to a scholarly journal. Structural Dynamics is a peer-reviewed, open access, online-only journal co-published by ACA and AIP Publishing. It highlights research articles on structural determination and dynamics of systems, enabled by the emerging new instruments (e.g. XFELs, high harmonic generation, ultra-short electron sources, etc.) and new experimental and theoretical methodologies. The journal is accepting short communications, topical reviews, and research papers in the following topics: Experimental Methodologies, Theory and Modeling, Surfaces and Interfaces, Materials, Liquids and Solutions, and Biological Systems.
