Abstract
â¶ Oxides are the best-known compounds in solid state chemistry and, ideally, provide a paradigm for other types of materials. â¶ Sulfides are not structurally related to oxides due to the larger covalency of the S2â anion compared to the O2â anion. â¶ However, for one-dimensional mixed-metal sulfides the ionic model can still describe structure and properties. â¶ A variety of magnetic and transport properties is found in one-dimensional sulfides. â¶ A rare example of low-spin configuration for tetrahedral Fe3+ in CsGa1âxFexS2. â¶ Negative magnetoresistance up to â¼10% recently reported in Ba2Co1âxZnxS3. â¶ Low-dimensional compounds, in general, are gaining more attention due to their similarities to nanowires.
