Hi Meital,
If you use the command "crystalcontacts" there is an option to list the residues in the Reply Log, for example, if your structure is open as model #0 and you want to use distance 2.5 Angstroms:

crystalcontacts #0 2.5 residueInfo true

See command help and list of options:
<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/crystalcontacts.html>

If you are considering switching to ChimeraX, note that ChimeraX also has a Crystal Contacts tool and a "crystalcontacts" command with the residueInfo option.

I hope this helps,
Elaine
