Hi You don't need a CIF file for elements or their ions, only for compounds. Li and Li+1 are already in the list of scattering factors ($CLIBD/atomsf.lib) as indeed are all the elements with their common ions. Are you sure you have the atom name in the right columns on the HETATM record (e.g. Li in 13-14 and LI1+ in 77-80)?
