Platon Taskbar

Platon is a general crystallographic tool implementing a large variety of standard geometrical calculations such as bonds, angles, torsions, planes, rings, inter-molecular contacts (H-Bond analysis), co-ordination etc., either fully automatic or as specified.

You can also perform ADDSYM tests. It also comes with utilities for cell transformation (SHELXL input and PDB & CIF output).

It can generate automatic labelled ORTEP-lookalike plots.
