Olex² is a simple to use program containing numerous tools for the structure analysis and publication, including Fourier maps and voids calculation and visualisation, space group determination, calculation of esd's for almost any possible geometrical parameters, CIF translation to HTML and other documents, hydrogen atom placement and many others. 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.
