The present chapter describes the main trends in the progress of inorganic tellurium chemistry during recent decades. The emphasis is on the synthesis and characterization of novel nonmetallic tellurium compounds and on transition metal compounds with tellurium‐containing ligands. Many inorganic tellurium compounds find use as single‐source precursors for the generation of binary telluride thin films for electronic applications, or as reagents in organic synthetic chemistry. The advent and progress in modern instrumental methods of analysis has shown that the structural features of tellurium compounds often differ from those of sulfur and selenium compounds.
