Dear Irini,
do you mean the program ATOMS by Eric Dowty?
Defining polyhedra in ATOMS is pretty straight forward by using
Input1/Polyhedra (I am referring to version 5.0).
Defining the no. of atoms or the size of the structure fragment
drawn is done in Input1/Boundary.
If you want to draw different polyhedra for identical cations then it
would be easiest to just change the type of atoms.
The inbuilt manual will help you in any other questions.
