Quoting their website:
"Olex² handles very complex crystallographic tasks through an intuitive GUI. The graphical user interface is the result of 10 years of striving to provide the best possible experience to modelling even the most challenging structures with ease.
The software originated at Durham University and has been in active development since 2004. Currently in development are extensions to improve productivity, some of which are already available to try out."
