The polyhedron needs a central atom. But you can add that yourself. The
command appears to be undocumented --
assign {attachmentAtom} "Symbol" {x y z}
For example:
assign atom {atomno=14} "Cl" {2 3 4}
That position {2 3 4} could also be an average position of a number of
atoms:
assign atom {atomno=14} "Cl" {2 3 4} {atomno=14 or atomno=13 or atomno=12
or atomno=11}
then you would also need to do the connections before creating the
polyhedra.
HOWEVER, with a bit of a tweak of Jmol, I can make this possible without
connecting the atoms. You will still need a central atom, though. Let me
get back to you on this.
