摘要：

New layered oxysulfides with alternating Cu2S2 and perovskite oxide layers have been synthesized and characterized. The perovskite oxide layers for Sr3Cu2Fe2O5S2 and Sr2CuMO3S (M = Cr, Fe, In) are (FeO2) (SrO) (FeO2) and (MO2) (SrO) (SrO) (MO2), respectively. All Fe, Cr, and In cations are in a square-pyramidal coordination geometry. Magnetic measurement shows an antiferromagnetic ordering at 60 K for Sr2CuCrO3S. (C) 1997 Academic Press.
