Notes:
N,N-Dimethylselenourea (DMSeU) yields, with TeX4 (X = Cl or Br), a variety of compounds having bonds from selenium to tellurium. Excluding molecules of solvation these compounds display the following stoichiometries: [(DMSeU)4Te]X2, (DMSeU)3(TeX4)2, and (DMSeU)2Te2X6. Tetramethylselenourea (TMSeU) gives, with TeBr4, crystals of (TMSeU)2TeBr4. Both the carbon-selenium and tellurium-halogen bonds undergo hydrolysis under mild conditions to yield precipitates that are alloys of selenium and tellurium. Thus, this group of compounds affords a new approach to the synthesis of selenium-tellurium alloys. Some of the properties of these compounds, as well as the crystal structure of [(DMSeU)4Te]Cl2, are described in this article.
