The pearceite-polybasite group of minerals (i.e., pearceite, antimonpearceite, arsenpolybasite, and polybasite) of general stoichiometry [M 6I T 2III S7][Ag 9I CuIS4], with M = Ag+, Cu+ and T = As3+, Sb3+, occur relatively commonly in nature. All have recently been shown to exhibit Ag + fast ion conduction at rather low temperatures (only slightly above or below room temperature). The average crystal structure determination of these materials shows the positions of the Ag+ ions to be smeared...[Show more]
