摘要: Publisher Summary This chapter provides an overview of sulfides, selenides, and tellurides. The rare earths form a very large number binary selenides tellurides, which belong to various crystal types. In the field ternary compounds, there are plenty compounds having special describes structural aspect earth chalcogenides. important evolution crystallochemical behavior R elements from lanthanum lutetium, leads distinct trend in composition structures their compounds. considers two main aspects: valence coordination atoms second characteristic considered is Two kinds sulfur (or selenium) polyhedra formed around earth. One kind related triangular prism, other derived octahedron.
