Abstract

A monophasic sample of Ag₂MnSn₃S₈ has been prepared by heating stoichiometric amounts of the constituent metals and sulfur in evacuated silica tubes at 670°C. Structural analysis of Ag₂MnSn₃S₈ using Rietveld refinement of powder X-ray diffraction data shows that it crystallizes in the Fd3̄m space group with a=10.6984(2)Å. Magnetization measurements in the temperature range 5-300K indicate paramagnetic behavior with a μ_eff of 5.80μ_B, consistent with the divalent nature of manganese. Electrochemical studies show a coulombic capacity of ∼50Ahkg^-1 for the cell constructed with Ag₂MnSn₃S₈ as the positive electrode.
