Otis and Dean,,

Thanks for the explanation. I was indeed able to find the whole command (spacefill ionic;lcaocartoon scale 1.0 CAP unitcell "cpk";spacefill off/) / in the documentation (in the "cpk" example of lcaoCartoons).

I think I understand it better now. The "spacefill" spheres are replaced with "cpk" spheres" which then are SLAB-ed (CAP-ed really) using "unitcell" as slabbing planes.

I tried it on NaCl (cif file). It works on a cell containing one Cl- in the center of the cell and one Na+ in the corner (which is properly CAP-ed).

However when I load {1 1 1} cell to get all ions within the cell, the Jmol (desktop Java app) freezes. I tried the newest version (14.13.1) an an older one (14.8.0) with the same results.

I tried Na (cif) (loading {2 2 2} and using "display unitcell" (which show all needed atoms), but "lcaocartoon scale 1.0 CAP unitcell "cpk";spacefill off" froze Jmol as well.

Any suggestions?

Thanks for your help.

Pshemak,

The CAP part is discussed here:

https://chemapps.stolaf.edu/jmol/docs/index.htm?&fullmanual=1&ver=14.6#isosurface

Scroll down until you see CAP listing.

The spacefill 1% is just hiding the atoms leaving the lcaocartoons

Dean, the main reason I'm jumping in here is the display unitcell command. Is that a legal Jmol Script command? After loading a CIF file, I thought that you had to do something like this to get the unit cell:

save orientation; load "" {444 666 1}; set displayCellParameters false;restore orientation; unitcell on; display cell=555; center visible; zoom 200;

Thank you Dean,

I do not understand the

lcaocartoon scale 1.0 CAP unitcell 'cpk'; spacefill 1%;

part of the command. Is it documented inhttps://chemapps.stolaf.edu/jmol/docs/ ?

Thanks,

PM

Yes - I have an example at: http://crystals.otterbein.edu/packing/index.html

Pick structure from the left menu and then click the “Show Contents of One Unit Cell”. Works beautifully!

The commands are:
display unitcell; spacefill ionic 100%; lcaocartoon scale 1.0 CAP unitcell 'cpk'; spacefill 1%;

Can the "slab" command be used to produce presentations equivalent to the image linked below?

If so, any suggestions on how to do that would be appreciated.

Thanks,
