How to Visualize Disorder in Mercury

Posted by

CCDC

This video introduces the free Disorder Analyser tool in CCDC’s Mercury and the options it provides for visualising disordered crystal structures. We will demonstrate how it is possible to switch between visible disorder groups with the click of a button, using examples of positional disorder, substitutional disorder, and disorder about special positions in structures with different numbers of disorder assemblies and groups.
