The layered, metallic scandium iodide Sc sub 0. 93 I sub 2 : Synthesis, structure, and properties

The stoichiometry of the layered metallic scandium iodide Sc{sub 0.93}I{sub 2}, reported earlier is confirmed. The compound was prepared by the reaction of ScI{sub 3} with excess metal over a sizeable temperature range; however, the composition was not detectably temperature dependent. Several prope...

Zusammenfassung:The stoichiometry of the layered metallic scandium iodide Sc{sub 0.93}I{sub 2}, reported earlier is confirmed. The compound was prepared by the reaction of ScI{sub 3} with excess metal over a sizeable temperature range; however, the composition was not detectably temperature dependent. Several properties of the material were measured, and the results are reported. The results of studies of the synthesis to clarify the structure through vapor-phase transport as well as Guinier powder and single crystal x-ray diffraction are reported. 21 refs., 2 tabs.
