Hej Henrique,

not an inorganic chemist here, but some suggestions anyway:

Metallic centers should be displayable as spheres using the *show*, or
*show_as spheres* commands. The radius can be altered using: *set
sphere_scale, value, selection*

The bonds are more problematic. Pymol has some options for editing bonds,
but a display as dotted line doesn't exist as such to my knowledge (maybe
something to expand on in future PyMOL versions?). What you could try is to
use distance objects instead, but depending on the complexity of the model
this may be applicable, or not. Note that you may have to unbond the
metallic center to remove any existing PyMOL bonds for the display.
http://pymolwiki.org/index.php/Distance

The distance objects can be colored and there are several settings related
to dashes, e.g. radius, shapes, gaps etc. etc (use the settings-->edit
all--> and filter by "dash").

Hope this may help, otherwise there may be other approaches,

Cheers,

Andreas
