Hi Yuan,
No worries. It is just a warning (if it is an error, MCPB.py will not finish the step). Not all of the metal ions (with various oxidation states) have VDW radii determined. Usually the cations of the same element have similar VDW radius, e.g. Fe2+ and Fe3+. Herein MCPB.py just tells it could not find the VDW radius for Os2+ and then it used the VDW radius of Os6+6 atom type (which is Os6+ ion) from UFF for the Os2+ ion the complex.
Kind regards,
Pengfei
