Abstract
The structure of a high ionic conductor Rb4Cu16I7.2Cl12.8 at low temperature has been reinvestigated
by use of angle-dispersive neutron powder diffraction.
The resulting nuclear-density maps have reconfirmed that Cu1Cu2 chains are the main conduction pathways in this material, as previously suggested from the Rietveld analysis of neutron powder diffraction data.
Journal Title and Volume Number (to be inserted by the publisher) 3 8 6 4 2 0 310280250220190160130100704010 T / K Present work Cu1 Cu2 Cu3 Kanno et. al.
These density images lead us to conclude that the Cu1Cu2 chain is the main conduction route in this material, as Kanno et al. pointed out.
